Tape recorders that normally record all of the air traffic monitoring stations on the operations floor at NORAD’s Northeast Air Defense Sector (NEADS) fail to record the positions of the two NEADS employees who are responsible for controlling the fighter jets launched from Otis Air National Guard Base in response to the hijacked Flight 11 (see 8:46 a.m. September 11, 2001). [9/11 Commission, 10/28/2003 ; 9/11 Commission, 7/24/2004, pp. 459; Shenon, 2008, pp. 203-204]No Recordings of Two Radio Channels - The 9/11 Commission Report will state that “there are no NEADS recordings available of the NEADS senior weapons director and weapons director technician position responsible for controlling the Otis [Air National Guard Base] scramble.” [9/11 Commission, 7/24/2004, pp. 459] According to an e-mail sent during the Commission’s investigation by Miles Kara, one of the Commission’s staff members, the two NEADS employees whose positions are not recorded are Steve Hedrick and Brad Gardner. Kara will write: “Since we have zero evidence of the voices of Hedrick and Gardner [on the recordings of the NEADS operations floor], the NORAD position that their channels were never recorded may be accurate.… We never hear them.” [9/11 Commission, 5/25/2004] The 9/11 Commission will state, however, that it “found a single communication from the weapons director or his technician on the guard frequency at approximately 9:11, cautioning the Otis fighters, ‘remain at current position [holding pattern] until FAA requests assistance’” (see 9:09 a.m.-9:13 a.m. September 11, 2001). Positions Not Recorded Due to 'Technical Issue' - The 9/11 Commission will say there are no recordings of the two positions because of “a technical issue,” although it will give no details of what that issue might be. [9/11 Commission, 7/24/2004, pp. 459] There are four Dictaphone multi-channel reel-to-reel tape recorders in a corner of the NEADS operations floor, which should be recording every radio channel. [Vanity Fair, 8/1/2006] These tape recorders are run by General Dynamics. Richard Crane is the technical representative of General Dynamics at NEADS who is responsible for the recordings on this day.

A number of key senior FAA personnel happen to be away from their usual bases this morning, at the time of the attacks. Bill Peacock, the FAA director of air traffic services, is in New Orleans for a meeting with the National Air Traffic Controllers Association (NATCA). Among his many duties, Peacock is “the ultimate manager of all the air traffic controllers in the country’s system.” He will be transported from New Orleans later in the day in an FAA business jet, one of the few aircraft permitted to fly, and only arrive at FAA headquarters shortly after 5:00 p.m. [Freni, 2003, pp. 12 and 70] Jack Kies, the FAA’s manager of tactical operations, is in Nashua, New Hampshire for a meeting with representatives of the Canadian air traffic control organization. [Freni, 2003, pp. 65-66] Consequently Linda Schuessler, the deputy director of system operations, has to take his place in charge of the FAA Command Center in Herndon, Virginia. [Federal Aviation Administration, 5/18/2006] Tony Ferrante, the manager of the FAA’s air traffic investigation arm, is in Chicago to testify at a hearing. He will become frustrated later in the day about being stuck there, knowing he should he at his post in Washington gathering forensic data on the hijackings and crashes. [Freni, 2003, pp. 7, 19 and 47-48] Rick Hostetler, a member of the FAA’s planning and procedures organization, is at the dentist’s in Waldorf, Maryland when the attacks begin. His job includes acting as the FAA’s primary air traffic liaison for the Secret Service, the US Special Operations Command, and the Pentagon. After seeing the second WTC tower hit live on television, reportedly while sitting in the dentist’s chair, he will quickly set out for his duty station at the FAA Command Center. But due to the heavy traffic, his journey will take hours and the attacks will be over by the time he gets there. [Freni, 2003, pp. 27, 47 and 90] Mike Canavan, the director of the FAA’s Office of Civil Aviation Security, is visiting the airport in San Juan, Puerto Rico. He will only make it back to Washington in the evening, on a special Army flight. [9/11 Commission, 5/23/2003] As part of his job, Canavan is the FAA’s hijack coordinator, responsible for requesting military assistance in the event of a hijacking (see 8:30 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 17-18] FAA Administrator Jane Garvey is in a breakfast meeting at the Department of Transportation, in Washington, DC. She will quickly relocate to FAA headquarters soon after the first attack (see (8:48 a.m.-9:05 a.m.) September 11, 2001). [Freni, 2003, pp. 62-63]Whether the absence of these senior personnel impairs the FAA’s ability to respond to the attacks is unknown.

At the District of Columbia Fire and EMS Training Academy, firefighters are taking part in what is described as a “counterterrorism class” or “antiterrorism exercises.” This is in preparation for the annual meetings of the International Monetary Fund (IMF) and the World Bank, which are scheduled to take place in Washington, DC, at the end of this month. Numerous individuals who will later respond to the attack on the Pentagon are in attendance. These include some firefighters with the Metropolitan Washington Airports Authority (MWAA) at Reagan National Airport. [CBS News, 9/17/2001; Goldberg et al., 2007, pp. 69 and 78] Captain Scott McKay of the Arlington County Fire Department (ACFD) is also reportedly “attending a counterterrorism class with the FBI in the District [of Columbia].” [Washington Post, 9/20/2001] And other ACFD personnel are reportedly “engaged in meetings in the District of Columbia, preparing for the upcoming International Monetary Fund (IMF) conference.” [US Department of Health and Human Services, 7/2002, pp. A4 ] FBI Special Agent Christopher Combs, who is the regular FBI liaison to the fire services and routinely cross-trains with regional departments, is at the Fire Academy, “training firefighters in counterterrorism tactics.” Combs serves on the FBI’s National Capital Response Squad (NCRS), an antiterrorism rapid response unit. [Goldberg et al., 2007, pp. 76] Members of the NCRS will be notified and recalled after the second WTC crash, and Combs will subsequently head to the Pentagon after hearing of the attack there, arriving at 9:49 a.m. [US Department of Health and Human Services, 7/2002, pp. C45 and 1-1 ]

Fire truck parked outside the Pentagon. [Source: Jon Culberson]Preparations are underway at the Pentagon heliport, located about 150 feet from the west side of the building, for the expected arrival of President Bush at around midday. Bush had left from the Pentagon the previous day for his visit to Florida. He occasionally uses the Pentagon heliport rather than the White House grounds when going by helicopter to and from Air Force One at Andrews Air Force Base. [Goldberg et al., 2007, pp. 64] The White House grounds are unavailable because the annual Congressional picnic is scheduled to take place there this afternoon. The White House hosts this event for members of Congress and select staffers; around 1,200 guests are due to attend, until the attacks lead to it being canceled. [Scripps Howard News Service, 9/11/2001; Scheib and Friedman, 2007, pp. 254-255; Hayes, 2007, pp. 344] Three firefighters from the fire department at nearby Fort Myer had arrived at the Pentagon at around 7:30 a.m. to man the fire station next to the heliport. [Newsweek, 9/28/2001; Journal of Emergency Medical Services, 4/2002, pp. 22 ; Goldberg et al., 2007, pp. 65] “Every day they have an aircraft flying, we’re there,” firefighter Alan Wallace will later explain. [Pentagram, 9/14/2001] Wallace decides to pull the fire truck out of the fire station and place it in a position more accessible to the heliport landing pad. [First Due News, 4/17/2003] The truck is equipped with the special chemical foam used in fighting jet fuel fires. [Goldberg et al., 2007, pp. 65] Wallace parks it about 15 feet from the Pentagon’s west wall, facing toward the landing pad. Wallace will recall that with many vehicles—belonging to the Secret Service and other agencies—expected to be around for the president’s arrival, he “wanted the crash truck out of the station and parked in a good location, for easy access to the heliport in case of an emergency.” [First Due News, 4/17/2003] When the Pentagon is hit at 9:37 a.m., the aircraft will crash into an area of the building next to the heliport (see 9:37 a.m. September 11, 2001).

NASA’s KC-135 in parabolic flight. [Source: NASA]A special aircraft operated by NASA is in the air over western New York State at the time of the terrorist attacks and, at one point, a large aircraft, which those on board later learn is the hijacked Flight 93, flies less than 1,000 feet below it. [Space Center Roundup, 9/2002 ] The plane, NASA 931, is a modified KC-135—a four-engine military aircraft similar to the Boeing 707. [National Aeronautics and Space Administration, 10/2000, pp. 28; National Aeronautics and Space Administration, 10/29/2004] It is used by NASA for reduced gravity research, and is known as the “Weightless Wonder” or sometimes the “Vomit Comet.” The aircraft creates weightless conditions for brief periods by flying up and down in large parabolic arcs. [NASAexplores, 1/30/2003] It is regularly operated from NASA’s Glenn Research Center in Cleveland, Ohio, next to Cleveland Hopkins International Airport, and usually flies four days a week. [National Aeronautics and Space Administration, 10/2000, pp. 140; National Journal's Technology Daily, 11/27/2002; National Aeronautics and Space Administration, 10/29/2004] A typical flight lasts two to three hours and consists of the plane flying 40 to 60 parabolas. [NASAexplores, 1/30/2003]Scientists from Houston Conducting Microgravity Experiments - A team of scientists from NASA’s Johnson Space Center in Houston, Texas, has flown to Cleveland to conduct microgravity experiments on the KC-135. [Cleveland Free Times, 9/6/2006] Dominic Del Rosso, the test director on the plane, will later recall that the team is flying over western New York State when the terrorist attacks occur. During the routine mission, the KC-135 cruises back and forth along the New York shore of Lake Ontario, climbing and descending to create a freefall condition to simulate microgravity. Del Rosso will comment, “To think that this type of maneuver might ever seem threatening never crossed my mind until [September 11].” The plane’s crew members are notified at some point that a large plane is intersecting their flight path less than 1,000 feet below them, instead of the usual 2,000-foot minimum distance. They will later learn that this aircraft is the hijacked Flight 93, which crashes in Pennsylvania (see (10:06 a.m.) September 11, 2001). Del Rosso will recall, “After the unwanted flyby, we landed having no idea why or what was going on.” [Space Center Roundup, 9/2002 ] The scientists are unable to return to Houston on this day, as scheduled, after the FAA orders all planes to land (see (9:45 a.m.) September 11, 2001), and so have to be put up in a hotel in Cleveland. [Cleveland Free Times, 9/6/2006]

Kirk Lippold. [Source: CNN]At the CIA headquarters in Langley, Virginia, three senior CIA officers—John Russack, Don Kerr, and Charlie Allen—are having breakfast with Navy Commander Kirk Lippold. Lippold was the commanding officer of the USS Cole when it was attacked in Yemen the previous year (see October 12, 2000). The men’s discussion is focused on terrorism. Lippold is upset that the American public still does not recognize the threat it poses, and says that it will take a “seminal event” to awaken them to the problem. Following the breakfast, Lippold heads to the Counterterrorist Center at CIA headquarters for some briefings. Just minutes later, after the WTC is hit, Charlie Allen will contact Lippold and tell him, “The seminal event just happened.” [Tenet, 2007, pp. 162-163]

Managers at the FAA’s Command Center in Herndon, Virginia, learn of the apparent hijacking of Flight 11, but continue with a meeting they are in for several minutes, until being notified that one of the plane’s flight attendants may have been stabbed. The daily staff meeting among all the department heads at the Command Center begins at 8:30 a.m. Ben Sliney, who is on his first day as national operations manager there, has just been informed of the suspected hijacking of Flight 11 (see 8:28 a.m. September 11, 2001). He begins the meeting by announcing news of the hijacking to the other managers, but then continues with his normal briefing, about the outlook for the coming day’s operations. Sliney is interrupted, apparently at around 8:40 a.m., when a supervisor enters the conference room and whispers to him that the situation with the hijacking has deteriorated: American Airlines has just called, reporting that a flight attendant on the plane may have been stabbed. Deciding he should be on the center’s operations floor rather than in the meeting, Sliney announces to the other managers: “Look, this hijack situation has seriously escalated and I need to get back to the floor. There is an unconfirmed report indicating that a flight attendant may have been stabbed.” He then excuses himself. The meeting is quickly broken up before the first World Trade Center crash occurs at 8:46 a.m. The managers then head to their posts. Despite the “intuitive nature of this group of people,” none of them will initially consider the first WTC crash to be connected to the hijacking they have been informed of. According to Linda Schuessler, the deputy director of system operations at the Command Center, “something that seemed so bizarre as flying a hijacked plane full of people into a skyscraper didn’t seem possible.” [Aviation Week and Space Technology, 12/17/2001; Freni, 2003, pp. 63; Spencer, 2008, pp. 1 and 19-21]

Offutt Air Force Base control tower during Global Guardian 1998. [Source: Jeffery S. Viano]As the 9/11 attacks are taking place, a large military training exercise called Global Guardian is said to be “in full swing.” It has been going on since the previous week. [Omaha World-Herald, 2/27/2002; Omaha World-Herald, 9/10/2002] Global Guardian is an annual exercise sponsored by US Strategic Command (Stratcom) in cooperation with US Space Command and NORAD. One military author defines Stratcom as “the single US military command responsible for the day-to-day readiness of America’s nuclear forces.” [Arkin, 2005, pp. 59]Exercise Tests Military's Ability to Fight a Nuclear War - Global Guardian is a global readiness exercise involving all Stratcom forces and aims to test Stratcom’s ability to fight a nuclear war. It is one of many “practice Armageddons” that the US military routinely stages. [Bulletin of the Atomic Scientists, 11/1/1997; Associated Press, 2/21/2002; Omaha World-Herald, 2/27/2002; Omaha World-Herald, 9/10/2002] It links with a number of other military exercises, including Crown Vigilance (an Air Combat Command exercise), Apollo Guardian (a US Space Command exercise), and the NORAD exercises Vigilant Guardian and Amalgam Warrior. [US Department of Defense, 5/1997; GlobalSecurity (.org), 4/27/2005] Global Guardian is both a command post and a field training exercise, and is based around a fictitious scenario designed to test the ability of Stratcom and its component forces to deter a military attack against the US. Hundreds of military personnel are involved. [US Congress, n.d.; Collins Center Update, 12/1999 ; Times-Picayune, 9/8/2002] The exercise involves “a lot of the elements of what ultimately would be the nuclear command and control system in support of a national emergency,” according to Admiral Richard Mies, the commander in chief of Stratcom. It includes an “exercise secretary of defense” and “an exercise president.” Mies will say that because of the exercise, “A lot of [Stratcom’s] command and control systems that, in peacetime, are normally not on alert were at a much, much higher state of alert [on September 11] and we had a number of aircraft, manned control aircraft that were airborne that were simulating their wartime roles.” [NET News, 12/27/2011]Exercise Normally Held in October or November - According to a 1998 Internet article by the British American Security Information Council—an independent research organization—Global Guardian is held in October or November each year. [Kristensen, 10/1998] In his book Code Names, NBC News military analyst William Arkin dates this exercise for October 22-31, 2001. [Arkin, 2005, pp. 379] And a military newspaper reported in March 2001 that Global Guardian was scheduled for October 2001. [Space Observer, 3/23/2001, pp. 2 ] If this is correct, then some time after March, the exercise must have been rescheduled for early September. Exercise Includes a 'Computer Network Attack' - Furthermore, a 1998 Defense Department newsletter reported that for several years Stratcom had been incorporating a computer network attack (CNA) into Global Guardian. The attack involved Stratcom “red team” members and other organizations acting as enemy agents, and included attempts to penetrate the command using the Internet and a “bad” insider who had access to a key command and control system. The attackers “war dialed” the phones to tie them up and sent faxes to numerous fax machines throughout the Command. They also claimed they were able to shut down Stratcom’s systems. Reportedly, Stratcom planned to increase the level of computer network attack in future Global Guardian exercises. [IAnewsletter, 6/1998 ] It is unclear if a computer network attack is incorporated into Global Guardian in 2001.

The air traffic control tower at Otis Air National Guard Base. [Source: CapeCodFD.com]Daniel Bueno, a supervisor at the FAA’s Boston Center, calls the air traffic control tower at Otis Air National Guard Base to alert it to the problems with Flight 11 and request military assistance. [Filson, 2003, pp. 47; Spencer, 2008, pp. 22] Otis Air Base, at Cape Cod, Massachusetts, is one of NORAD’s seven alert sites in the continental United States, which keeps two armed fighter jets ready for immediate takeoff. [Filson, 2003, pp. 50; 9/11 Commission, 7/24/2004, pp. 17]Supervisor Calls Otis, Violating Protocol - Bueno calls the control tower at Otis even though, according to author Lynn Spencer, he “knows it’s not standard operating procedure to call the military directly—that’s supposed to be done by FAA headquarters.” But he has “checked the FAA regulation manual, and in the back under section FAAO 7610.4J, Appendix 16, it states that fighters can be launched directly at FAA request, so he is going to make that happen. He may not be FAA headquarters, but he is FAA!” [Spencer, 2008, pp. 22]Bueno Requests Fighters, Told to Call NEADS - Bueno tells the controller at the Otis tower that Flight 11 has lost its identification signal and appears to be headed toward Manhattan; it looks like a possible hijacking, and fighter jets are needed, fast. [Filson, 2003, pp. 47] But the controller tells Bueno that he must follow the protocol, which is to contact NORAD’s Northeast Air Defense Sector (NEADS). The controller says: “You’ve got to go through the proper channels. They’re the only ones with the authority to initiate a scramble order.” [Spencer, 2008, pp. 22] Bueno asks the controller for the telephone number for NEADS. [102nd Fighter Wing, 2001] Following this call, the tower controller will contact the Otis Air Base operations desk, to let it know that it might be receiving a call from NEADS (see (Between 8:31 a.m. and 8:40 a.m.) September 11, 2001). [Spencer, 2008, pp. 27]Otis Pilots Critical of Bueno - The two alert pilots at Otis Air Base will later criticize Bueno for calling the base directly. One of them, Major Daniel Nash, will complain: “It sounds like the FAA didn’t have their [act] together at all when they were calling the [Otis] tower.… To me, it sounded like there was someone who didn’t know what they were doing.” [Boston Globe, 9/11/2005] Lieutenant Colonel Timothy Duffy, the other alert pilot, will comment: “It didn’t happen the way it was supposed to.… We were the ones who were contacted right away and knew about it before the air defense sector.” [Filson, 2003, pp. 50]Time of Call Unclear - Bueno also calls the FAA’s Cape Terminal Radar Approach Control (TRACON), which is located on Otis Air Base, at 8:34 a.m. and requests that fighters be launched from Otis (see 8:34 a.m. September 11, 2001). [Federal Aviation Administration, 4/19/2002; 9/11 Commission, 9/22/2003 ] Whether he makes that call before or after he calls the Otis tower is unstated. According to the 9/11 Commission Report, “the first notification received by the military—at any level—that American 11 had been hijacked” is when the FAA’s Boston Center calls NEADS just before 8:38 a.m. (see (8:37 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20] If that is correct, it would indicate that Bueno calls the Otis tower after he calls the Cape TRACON.

Gerard Arpey. [Source: American Airlines]Gerard Arpey, American Airlines’ executive vice president of operations, learns of the trouble on Flight 11 and then heads to the airline’s System Operations Control (SOC) center, but he is unable to contact the airline’s president to alert him to the crisis at this time. [9/11 Commission, 1/8/2004 ]Arpey Told about Call from Flight Attendant - At around 8:30 a.m., Arpey, who is in his office at American Airlines’ headquarters in Fort Worth, Texas, makes a routine phone call to the nearby SOC. [9/11 Commission, 1/27/2004; 9/11 Commission, 8/26/2004, pp. 12] The call is answered by Joseph Bertapelle, the manager of SOC operations coordination/air traffic systems. [9/11 Commission, 1/8/2004 ] Bertapelle tells Arpey about a phone call the airline has received from Betty Ong, a flight attendant on the hijacked Flight 11. [9/11 Commission, 1/27/2004; 9/11 Commission, 8/26/2004, pp. 12] Since 8:18 a.m., Ong has been on the phone with employees at the American Airlines Southeastern Reservations Office in North Carolina (see 8:18 a.m. September 11, 2001), and one of those employees has been relaying the information Ong provides to Craig Marquis, the manager on duty at the SOC (see (8:21 a.m.) September 11, 2001). [9/11 Commission, 11/19/2003 ; 9/11 Commission, 8/26/2004, pp. 8-9]Arpey Wonders if Ong's Call Is Genuine - Bertapelle tells Arpey that Marquis has learned that Ong said there were “bad guys” on her plane and a flight attendant had been stabbed. Arpey wonders if the call from Ong is genuine. Considering the number of “crank” calls the airline receives, he will later comment, he is “conditioned to be somewhat skeptical.” However, when Bertapelle says Ong has reported a cockpit intrusion (see 8:22 a.m.-8:24 a.m. September 11, 2001), this information makes Arpey think “that the incident could be the real thing.” Arpey Unable to Reach Airline's President - Immediately after the call with Bertapelle ends, Arpey tries calling Don Carty, the president of American Airlines, to let him know what is happening. [9/11 Commission, 1/8/2004 ; 9/11 Commission, 8/26/2004, pp. 12] But Carty is at home answering e-mails and so has not yet arrived at his office. Arpey therefore leaves a message, requesting that Carty call him as soon as possible. Arpey Heads to Operations Center, Learns Details of Hijacking - Arpey briefs his executive assistant on what he has learned about the trouble on Flight 11. [Wall Street Journal, 10/15/2001; 9/11 Commission, 1/27/2004] He then heads to the SOC, along with Dan Huffman, American Airlines’ senior vice president of maintenance and engineering. [9/11 Commission, 1/8/2004 ] The SOC is about a mile away from the airline’s headquarters, and Arpey will recall that he arrives there at between 8:35 a.m. and 8:40 a.m. After he reaches the SOC, managers there tell him they are now treating Flight 11 as a confirmed hijacking. Arpey is told that the plane’s pilots are still not responding to calls from the flight attendants and that Ong said a passenger in first class had been stabbed, possibly fatally (see 8:33 a.m. September 11, 2001). He learns that the FAA has notified the airline that, instead of heading west on its intended flight path, Flight 11 is heading south; the plane’s transponder has been turned off; and the pilots are not responding to radio calls (see 8:29 a.m. September 11, 2001). [9/11 Commission, 1/27/2004] Arpey also learns that airline managers are setting up the System Operations Command Center in order to deal with the emergency (see (Between 8:40 a.m. and 8:55 a.m.) September 11, 2001), and because they are doing this, he will say, he “knew that they had concluded the incident was real.” [9/11 Commission, 1/8/2004 ; 9/11 Commission, 8/26/2004, pp. 12] As executive vice president of operations, Arpey is responsible for American Airlines’ worldwide flight operations, and he will therefore be directly involved in the airline’s subsequent emergency response efforts and other operational decisions throughout the day.

Neal Baer. [Source: Physicians for Social Responsibility-Los Angeles]A group from NBC is in New York, near the World Trade Center, doing preparatory work for a drama miniseries about al-Qaeda committing a series of terrorist attacks in the city. [Variety, 9/10/2001; Hollywood, Health and Society, 4/2/2002 ; CNN, 9/9/2002; USA Today, 12/5/2002] The big-budget five-hour miniseries, called Terror, will combine the casts of all three of NBC’s Law & Order crime drama series: the original show, Law & Order: Special Victims Unit, and Law & Order: Criminal Intent. It is intended to be broadcast in May 2002. Its storyline follows a devotee of Osama bin Laden who goes from an al-Qaeda training camp in Afghanistan to New York. There, he sets off explosives in the subway under Times Square, killing over 1,000 people. A bioterrorist release of anthrax is subsequently discovered. [Variety, 9/10/2001; Los Angeles, 4/2002; USA Today, 12/5/2002]Group Doing Planning Work for Show - This morning, Neal Baer, one of Law & Order’s executive producers, is in New York with some of his colleagues, doing preproduction planning for Terror. The group is at a facility at Chelsea Piers, on Manhattan’s West Side, only a couple of miles from the WTC. Baer and his colleagues are “ironing out details” for the miniseries, according to CNN. After the attacks on the WTC take place, they will watch in shock as people run up the West Side Highway, “first panicky groups fleeing the initial hit, then ash-covered survivors of the towers’ collapse.” [Hollywood, Health and Society, 4/2/2002 ; CNN, 9/9/2002]Magazine Has Front-Page Story about Show - Writers have been working on Terror for several months (see June-September 11, 2001) and filming is scheduled to begin later this month. [Los Angeles, 4/2002; Hollywood, Health and Society, 4/2/2002 ] This morning, Variety magazine even has a front-page story about the miniseries. [Variety, 9/10/2001; CNN, 9/9/2002] But Terror will be canceled less than a week after the 9/11 attacks. The show’s producers will say that it would be “[i]nappropriate to produce the Law & Order miniseries dealing with terrorists, dealing with terrorism, in light of the horrifying events that have unfolded over the past week.” [Variety, 9/17/2001]

A large training event is being held at the US Park Police Aviation Unit in preparation for the upcoming meetings of the International Monetary Fund (IMF) and the World Bank in Washington, DC, on September 29-30, and some of the participants will later be involved in the emergency response to the terrorist attacks. [International Monetary Fund, 9/17/2001; Reuters, 9/17/2001; US Naval Historical Center, 11/19/2001; McDonnell, 2004, pp. 18-20 ] The Park Police Aviation Unit is located in Anacostia Park in southeast Washington, across the Potomac River from the Pentagon. [Aviation International News, 10/1/2001; National Park Service, 10/16/2004]Event Preparing for Possibly Violent Demonstrations - According to Sergeant Ronald Galey, a helicopter pilot with the aviation unit, because of the preparations taking place for the IMF and World Bank meetings, “it started out to be a little bit of an unusual day.” [US Naval Historical Center, 11/20/2001] Sergeant Keith Bohn, another Park Police helicopter pilot, will later recall, “As fate would have it, we were having a large training event right out in front of the building here [the aviation hangar in Anacostia Park] for the upcoming IMF, the International Money Fund demonstrations.” Consequently, there are “horse-mounted officers, motorcycle officers, ground troops all training together to handle the movement of large groups of people.” [US Naval Historical Center, 11/19/2001] According to Galey, “[W]e all anticipated” the protest demonstrations at the IMF and World Bank meetings “to be very violent, very different than anything we’ve had in a long time.” [US Naval Historical Center, 11/20/2001]Helicopter Pilot Giving 'Riot Training' - Another of the aviation unit’s helicopter pilots, Sergeant Kenneth Burchell, is reportedly “conducting riot training… in preparation for the upcoming World Bank/International Monetary Fund protest demonstrations.” The riot training is being attended by 40 police officers belonging to an (unnamed) force other than the Park Police, along with some Department of Defense medical personnel. [McDonnell, 2004, pp. 18-20 ]Medical Personnel Participating in Training - Personnel from the Casualty Care Research Center (CCRC)—a medical outfit from the Uniformed Services University of the Health Sciences (USUHS) in Bethesda, Maryland—are attending the training event at the aviation unit. The CCRC provides medical support to law enforcement agencies and their “protectees” during emergencies. [US Medicine, 10/2001] One of these personnel, Jason Kepp, is reportedly teaching members of the Park Police “how to respond safely and effectively to the crowds of demonstrators expected to turn out at the upcoming meeting of the International Monetary Fund.” [USU Medicine, 12/2002 ]Training Participants Involved in Response to Attacks - The Park Police Aviation Unit will be among the first agencies to respond to the Pentagon attack at 9:37 a.m. (see Shortly After 9:37 a.m. September 11, 2001). [Goldberg et al., 2007, pp. 161] Two medics from the USUHS who are attending the training event—Kepp and his colleague, Keith Kettell—will take off in the second Park Police helicopter to launch following the Pentagon attack, so as to assist in the emergency response. [USU Medicine, 12/2002 ; McDonnell, 2004, pp. 20 ] In addition to members of their own force, Park Police commanders will deploy the 40 police officers attending the riot training at the aviation unit when the attacks occur. [McDonnell, 2004, pp. 18 ] Members of firefighting agencies that later respond to the attack on the Pentagon are also involved in preparations for the upcoming IMF and World Bank meetings this morning (see 8:30 a.m. September 11, 2001 and 8:30 a.m. September 11, 2001).

Mike Canavan testifying before the 9/11 Commission. [Source: C-SPAN]Protocols in place on 9/11 state that if the FAA requests the military to go after an airplane, “the escort service will be requested by the FAA hijack coordinator by direct contact with the National Military Command Center (NMCC).” [Federal Aviation Administration, 11/3/1998] Acting FAA Deputy Administrator Monte Belger states essentially the same thing to the 9/11 Commission, “The official protocol on that day was for the FAA headquarters, primarily through the hijack coordinator… to request assistance from the NMCC if there was a need for [Defense Department] assistance.” [9/11 Commission, 6/17/2004] However, the hijack coordinator, FAA Office of Civil Aviation Security Director Mike Canavan, is in Puerto Rico and claims to have missed out on “everything that transpired that day.” The 9/11 Commission fails to ask him if he had delegated that task to anyone else while he was gone. [9/11 Commission, 5/23/2003; 9/11 Commission, 7/24/2004, pp. 17] Monte Belger will later say simply that “an FAA security person” runs the “hijack net” open communication system during 9/11.

Captain Charles Leidig.
[Source: US Navy]Brigadier General Montague Winfield, the deputy director for operations (DDO) in the National Military Command Center (NMCC) at the Pentagon, leaves his post to attend a pre-scheduled meeting, allowing a colleague, who only recently qualified to take over his position, to stand in for him, and not returning to his post until after the terrorist attacks have ended. [9/11 Commission, 7/21/2003 ; 9/11 Commission, 4/29/2004 ; 9/11 Commission, 6/17/2004]Winfield Attends Air Force-Convened Meeting - Winfield leaves his post to attend what a 9/11 Commission memorandum will call “an unrelated, closed-door personnel meeting convened by the Air Force to discuss the rating of Air Force officers.” [9/11 Commission, 7/21/2003 ] Another Commission memorandum will state that this meeting is a “session for general officers who rated Air Force officers.” It is unclear whether the meeting takes place somewhere in the NMCC or outside the center. The Commission memorandum will only say that it takes place “elsewhere in [Joint Chiefs of Staff] spaces.” At least one of the NMCC’s other qualified DDOs, Brigadier General Norman Seip, is also attending it. Winfield Asked Colleague to Replace Him on Previous Day - Winfield is temporarily replaced as DDO by Captain Charles Leidig. Leidig only joined the operations directorate of the Joint Chiefs of Staff in July 2001, when he assumed duties as the deputy for Command Center operations. In that, his usual role, he is responsible for the maintenance, operation, and training of watch teams for the NMCC. He qualified to stand in as the DDO in the NMCC about a month ago, in August 2001. The previous afternoon, Winfield asked Leidig to relieve him for a portion of his duty this morning, and Leidig agreed to do so. Leidig Takes Over as DDO - As arranged, Leidig takes over from Winfield as DDO at 8:30 a.m., allowing Winfield to attend his meeting. Upon arrival at the NMCC, Leidig receives the intelligence and other turn over briefings. After seeing the reports of the plane crashes in New York on television, he will be responsible for convening a significant event conference (see 9:29 a.m.-9:34 a.m. September 11, 2001), which he soon upgrades to an air threat conference (see 9:37 a.m.-9:39 a.m. September 11, 2001). [9/11 Commission, 4/29/2004 ; 9/11 Commission, 6/17/2004 ]Winfield Does Not Resume Duties until Attacks Are Over - Even though it becomes obvious that a coordinated attack is under way when television shows the second plane hitting the World Trade Center at 9:03 a.m. (see 9:03 a.m. September 11, 2001), Winfield apparently remains in his meeting instead of resuming his duties as DDO (see (Shortly After 9:03 a.m.) September 11, 2001). He will only take over from Leidig as DDO after Flight 93 crashes in Pennsylvania, apparently at around 10:30 a.m. (see (10:30 a.m.) September 11, 2001). [9/11 Commission, 4/29/2004 ; 9/11 Commission, 6/17/2004] In later interviews for television, Winfield will give the impression that he remained in charge of the NMCC throughout the 9/11 attacks, and make no mention of having allowed a stand-in to take his place during this most critical period of time.

The battle cab at NORAD’s Northeast Air Defense Sector (NEADS) is staffed this morning due to the sector’s participation in the training exercise, Vigilant Guardian. [9/11 Commission, 10/28/2003 ; 9/11 Commission, 10/30/2003 ; Jones, 2011, pp. 24] The battle cab is a glass-walled command area that overlooks the NEADS operations floor. [Filson, 2003, pp. 55; 9/11 Commission, 7/24/2004, pp. 460] The “battle staff”—presumably the personnel working in it—is only formed when a training exercise or an “air defense event” is underway, according to Lieutenant Colonel Dawne Deskins, who is on duty in the battle cab. [9/11 Commission, 10/30/2003 ] Because NEADS is currently participating in an exercise, therefore, the battle cab is manned this morning. [9/11 Commission, 10/30/2003 ] “If the exercise had not been planned, there would not have been any staffing in the battle cab,” Lieutenant Colonel Ian Sanderson, who is also in the battle cab this morning, will later say. He will add that if a battle cab has not already been formed and is required, it would be necessary to call the NEADS director of operations in order to arrange for one to be set up. Forming a battle cab would only take a few minutes once it is understood that a serious incident is taking place, according to Sanderson. Sanderson will comment that if the battle staff had not already been in place when the terrorist attacks began this morning, the NEADS operations floor would still have functioned the same way. But the advantage of already having the battle staff in place is that “key figures of authority [are] there and ready to respond” when NEADS learns of the crisis. [9/11 Commission, 10/29/2003 ] Vigilant Guardian is a major annual air defense exercise simulating an attack on the United States (see (6:30 a.m.) September 11, 2001). Across NORAD, “from Alaska to Canada and throughout the continental United States,” author Leslie Filson will describe, “battle staffs [are] poised to fight the simulated air war” this morning, due to their participation in it.

A number of pilots with the 102nd Fighter Wing at Otis Air National Guard Base in Massachusetts are preparing to take off for a training mission and see two of their unit’s fighter jets being scrambled in response to the hijacked Flight 11, but they are not asked to respond to the emerging crisis themselves and continue with their preparations for the training mission. [102nd Fighter Wing, 2001; Richard, 2010, pp. 9-12]Pilots Preparing for Training over the Atlantic - The pilots are preparing to fly a defensive counter-air mission in an area of military training airspace over the Atlantic Ocean, southeast of Long Island, known as “Whiskey 105.” [Richard, 2010, pp. 10, 12; Airman, 9/3/2011] According to most accounts, six of the 102nd Fighter Wing’s F-15 fighters will be participating in the training mission. [102nd Fighter Wing, 2001; North American Aerospace Defense Command, 9/11/2001; Cape Cod Times, 9/11/2006; Spencer, 2008, pp. 155] But Major Martin Richard, one of the pilots involved, will write in a 2010 book that eight of the unit’s F-15s take part in the mission. Richard will recall that after the coordination briefing for the training mission, he goes to the “life support shop” and puts on his flying gear, and then goes to the operations desk. There, the unit’s supervisor of flying, Lieutenant Colonel Jon Treacy, briefs the pilots preparing for the training mission on current weather and airfield updates, and gives them the status of a KC-135 tanker plane that will be refueling their fighters during the training mission. Richard then heads to his F-15, inspects it, and speaks to his crew chief. Pilots Notice Commotion as Fighters Are Scrambled - As Richard starts his fighter’s engines, he notices a commotion on one side of the flight line ramp. He will recall: “The broken, disjointed communication over the ultra high frequency (UHF) radio indicated confusion. Members of the 102nd Security Forces Squadron, the cops, marshaled into protective positions. Two vehicles appeared with their blue emergency lights flashing. We all knew what was going on.” The 102nd Fighter Wing keeps a pair of F-15s on alert—armed, fueled up, and ready to take off within minutes of a scramble order—and, Richard will recall, “[T]he alert aircraft were being scrambled.” [Richard, 2010, pp. 10-11]Pilots Watch Alert Fighters Take Off, but Unconcerned about This - The pilots preparing to take off for the training mission idle their engines and wait while the two alert fighters take off (see 8:46 a.m. September 11, 2001). [102nd Fighter Wing, 2001] Richard will describe: “I watched from my jet as the clamshell doors on the alert hangars opened, heard the alert jets’ engines whine to life, and saw them aggressively emerge from the facility like an eager predator in search of its prey. Suddenly, the command post announced, ‘Scramble!’ They blasted off, shattering the previously still, calm, peaceful morning.” [Richard, 2010, pp. 12] The pilots involved in the training mission are apparently unaware of why these fighters are being scrambled. [Cape Cod Times, 9/11/2006] Richard will recall: “I wasn’t too concerned when I saw the scrambled aircraft take off. We see many scrambles during the year and most all are just aircraft or vessels that can’t be identified but are friendly.” [102nd Fighter Wing, 2001]Pilots Continue Preparing for Training - Once the two alert fighters are airborne, the pilots on the ground continue preparing for their training mission. “Back on the flight line,” Richard will recall, “I arranged my formation for takeoff and followed the standard procedures en route to our training area southwest of Martha’s Vineyard.” [Richard, 2010, pp. 12] Richard and the other pilots will begin their training mission in Whiskey 105 (see (9:00 a.m.-9:24 a.m.) September 11, 2001). They will only learn of the first crash at the World Trade Center and be recalled to their base at around 9:25 a.m. (see (9:25 a.m.-9:45 a.m.) September 11, 2001), and some of them will take off again to help protect US airspace, but that will only be after the terrorist attacks have ended (see (10:30 a.m.) September 11, 2001 and (Shortly After 10:30 a.m.) September 11, 2001). [102nd Fighter Wing, 2001; 9/11 Commission, 10/14/2003 ; Spencer, 2008, pp. 244-246]Unit's Mission Is to Protect Northeast US - The 102nd Fighter Wing at Otis Air Base, according to its own statement, has aircraft and their crews “on continuous 24-hour, 365-day alert to guard our skies.” The unit says its “mission is to protect the Northeast United States from armed attack from another nation, terrorist attack, and activities such as smuggling, illicit drug activity, and illegal immigration.” Its large area of responsibility includes “the major industrial centers of Boston, New York, Philadelphia, Detroit, and all national command centers in Washington, DC.” [Cape Cod Times, 9/12/2001] The 102nd Fighter Wing is equipped with 18 F-15 Eagles, including the two that are kept on alert.

Lieutenant Colonel Timothy Duffy. [Source: CBC]After being informed of the possible hijacking of Flight 11, an air traffic controller in the control tower at Otis Air National Guard Base calls the base’s operations desk to let it know that it might be receiving a call from NORAD’s Northeast Air Defense Sector (NEADS). [Spencer, 2008, pp. 27-28] Daniel Bueno, a supervisor at the FAA’s Boston Center, has just called the control tower at Otis Air Base, at Cape Cod, Massachusetts, alerting it to the problems with Flight 11 and requesting military assistance. The controller who took the call told Bueno he needed to call NEADS in order to get fighter jets launched (see (Between 8:30 a.m. and 8:40 a.m.) September 11, 2001). [Filson, 2003, pp. 47; Spencer, 2008, pp. 22]Tower Controller Calls Operations Desk - According to author Lynn Spencer, the tower controller subsequently “figures a call [to Otis Air Base] will be coming from NEADS soon and a scramble order is likely. He knows the fighter pilots will appreciate the heads-up.” He therefore calls the Otis Air Base operations desk. According to Spencer, the phone is answered by Master Sergeant Mark Rose, who is the superintendent of aviation management, in charge of flight records and currency for the pilots of the 102nd Fighter Wing. [Spencer, 2008, pp. 27] But according to the 102nd Fighter Wing’s own history of the 9/11 attacks, the call is answered by a Technical Sergeant “Margie Woody.” [102nd Fighter Wing, 2001]Controller Confuses Superintendent - Rose (or Woody, if the wing’s account is correct) is initially confused by the call. The tower controller does not identify himself or say where he is calling from, but instead begins by asking, “What do you have available?” As Spencer will describe, “For all [Rose] knows, this could be a wrong number or a crank call,” so rather than giving information about the base, Rose responds, “What are you talking about?” The controller then identifies himself and explains that he has just received a report about a hijacking. Rose realizes he needs to pass the call on to someone more appropriate. Pilot Informed of Hijacking - Pilot Lieutenant Colonel Timothy Duffy, who is the director of operations for the 102nd Fighter Wing, is standing next to Rose by the operations desk. Rose tells him, “Duff, you got a phone call,” and then says the caller is “Otis tower—something about an apparent hijacking under way: American 11, a 767, out of Boston and headed for California.” [Spencer, 2008, pp. 27-28] Duffy will later recall his response to this news: “As soon as we heard there was something about a hijacking we got moving.” [Filson, 2003, pp. 50] On his handheld radio he calls Major Daniel Nash, who along with Duffy is an “alert” pilot on duty at this time, and instructs him to suit up ready for any scramble call. [Spencer, 2008, pp. 28] The two pilots will run to the nearby locker room, put on their G-suits and helmets, and then head out toward their jets (see (8:40 a.m.) September 11, 2001). [Cape Cod Times, 8/21/2002; Boston Globe, 9/11/2005] Meanwhile, a commander at Otis will phone NEADS to report the FAA’s request for military assistance (see Shortly After 8:37 a.m. September 11, 2001). Call Is Not 'the First Notification Received by the Military' - The exact time the tower controller calls the operations desk at is unclear. Duffy will later guess that the call occurs “at about 8:30, 8:35.” [Filson, 10/22/2002; Filson, 2003, pp. 50] But according to the 9/11 Commission Report, “the first notification received by the military—at any level—that American 11 had been hijacked” is when the FAA’s Boston Center calls NEADS just before 8:38 a.m. (see (8:37 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20] According to the102nd Fighter Wing’s history of the 9/11 attacks, the call to the operations desk is made at 8:38 a.m. [102nd Fighter Wing, 2001] Bueno also called the FAA’s Cape Terminal Radar Approach Control (TRACON), which is located on Otis Air Base, at 8:34 a.m., to request that fighters be launched from Otis (see 8:34 a.m. September 11, 2001), and in response, the TRACON contacts the Otis tower and operations desk (see (8:36 a.m.-8:41) September 11, 2001).

FAA headquarters in Washington, DC. [Source: FAA]Four minutes after it is informed of the suspected hijacking of Flight 11 (see 8:28 a.m. September 11, 2001), the FAA Command Center in Herndon, Virginia, passes on word of the hijacking to the operations center at FAA headquarters in Washington, DC. The headquarters is apparently already aware of the hijacking, as the duty officer who speaks with the Command Center responds that security personnel at the headquarters have just been discussing it on a conference call with the FAA’s New England regional office. [9/11 Commission, 7/24/2004, pp. 19; 9/11 Commission, 8/26/2004, pp. 11] According to the 9/11 Commission, “FAA headquarters is ultimately responsible for the management of the national airspace system,” and the operations center there “receives notifications of incidents, including accidents and hijackings.” FAA headquarters has a hijack coordinator, who is “the director of the FAA Office of Civil Aviation Security or his or her designate.” Procedures require that, if a hijacking is confirmed, the hijack coordinator on duty is “to contact the Pentagon’s National Military Command Center (NMCC) and to ask for a military escort aircraft to follow the flight, report anything unusual, and aid search and rescue in the event of an emergency.” Yet, the Commission will state, although “FAA headquarters began to follow the hijack protocol,” it does “not contact the NMCC to request a fighter escort.” [9/11 Commission, 7/24/2004, pp. 16-19] Mike Canavan, who would normally be the FAA’s hijack coordinator, is away in Puerto Rico this morning, and it is unclear who—if anyone—is standing in for him in this critical role (see 8:30 a.m. September 11, 2001). [9/11 Commission, 5/23/2003; 9/11 Commission, 7/24/2004, pp. 17]

Michael Woodward, a manager at the American Airlines flight services office at Logan International Airport in Boston, instructs a colleague to find out the details of three hijackers on Flight 11, based on their seat numbers, but it is unclear whether his colleague is then able to identify the hijackers. [ABC News, 7/18/2002; New York Observer, 2/15/2004] Since 8:32 a.m., Woodward has been on the phone with Amy Sweeney, a flight attendant on Flight 11, who has been describing to him the trouble on her plane (see (8:32 a.m.-8:44 a.m.) September 11, 2001). [9/11 Commission, 8/26/2004, pp. 11] During the call, she says that the men who hijacked her plane were in seats 9D, 9G, and 10B. [9/11 Commission, 1/25/2004 ] According to the New York Observer, Woodward then orders a colleague “to punch up those seat locations on the computer.” [New York Observer, 2/15/2004] This enables airline personnel “to pull up [the hijackers’] names, phone numbers, addresses—and even credit card numbers—on the reservations computer,” according to ABC News. ABC News will add, “One of the names that came up was Mohamed Atta,” the name of the lead hijacker. [ABC News, 7/18/2002] However, apart from 10B—the number of the seat belonging to Satam Al Suqami—the seat numbers provided by Sweeney are different to the numbers of the seats assigned to the hijackers. The five hijackers on Flight 11 were in seats 2A, 2B, 8D, 8G, and 10B, according to the 9/11 Commission Report. Atta was in seat 8D—not one of the seats mentioned by Sweeney. [Los Angeles Times, 9/20/2001; 9/11 Commission, 7/24/2004, pp. 2] It is therefore unclear whether American Airlines is able to determine the identities of any of the hijackers, other than, presumably, Al Suqami, at this time. Evelyn Nunez, a passenger service agent at the American Airlines flight services office, was provided with the seat number of Al Suqami, but none of the other hijackers, when she talked with Sweeney in an earlier call, at 8:25 a.m. (see 8:25 a.m. September 11, 2001). By running a computer check, she was able to determine Al Suqami’s identity from this number. [Federal Bureau of Investigation, 9/11/2001, pp. 57-58] Nancy Wyatt, another employee in the flight services office, will pass on the three hijackers’ seat numbers provided by Sweeney to the American Airlines System Operations Control center in Fort Worth, Texas, when she calls it at 8:40 a.m. (see 8:40 a.m.-8:48 a.m. September 11, 2001). [American Airlines, 9/11/2001, pp. 34-41; 9/11 Commission, 8/26/2004, pp. 14]

Craig Marquis, the manager on duty at the American Airlines System Operations Control (SOC) center in Fort Worth, Texas, is told details of the crisis with Flight 11 that have just been received from the FAA’s Boston Center, and this information leads American Airlines to suspect that Flight 11 has been hijacked. [9/11 Commission, 8/26/2004, pp. 12] Minutes earlier, Marquis instructed Bill Halleck, an air traffic control specialist at the SOC, to contact the Boston Center to find out what was happening with Flight 11, and Halleck has just done so (see 8:29 a.m. September 11, 2001). [9/11 Commission, 1/8/2004 ; 9/11 Commission, 4/26/2004 ] Halleck now calls Marquis and tells him what he learned about Flight 11 from his call with the Boston Center. He says the aircraft is at “29,000 feet. They’ve lost comm [communications] with ‘em. Turned off his transponder. Tracking his primary [radar track] only. Was westbound. Turned southbound. Said the controller heard on the [radio] frequency, the pilot apparently adjust his mike… lot of loud voices… that sounded threatening.” Halleck then tells Marquis the details of this possible threat in the cockpit of Flight 11 that the Boston Center heard over radio. He says, “Something about ‘return or I’ll kill ya,’ or something to that effect… or threatening dialogue.” Halleck adds that he asked the Boston Center to pass on to the SOC “any information or updates” it subsequently receives. After Marquis hears this information from Halleck, he asks Halleck to “pull” Flight 11 up on his aircraft situation display. Following Halleck’s report to Marquis, American Airlines “now suspected that Flight 11 had been hijacked,” according to the 9/11 Commission.

Cape TRACON. [Source: FAA]Daniel Bueno, a supervisor at the FAA’s Boston Center, contacts the FAA’s Cape Terminal Radar Approach Control (TRACON), located on Otis Air National Guard Base at Cape Cod, Massachusetts, to alert it to the possible hijacking of Flight 11 and request that it arrange for military assistance in response. [Federal Aviation Administration, 9/17/2001 ; Federal Aviation Administration, 4/19/2002; 9/11 Commission, 2004; 9/11 Commission, 7/24/2004, pp. 20]Bueno Requests Fighters - After his call is initially answered by an air traffic controller at the Cape TRACON, Bueno is quickly passed on to Tim Spence, an operational supervisor at the facility. Bueno says, “I have a situation with American 11, a possible hijack.” He adds that Flight 11 “departed Boston, going to LAX [Los Angeles International Airport]. Right now he’s south of Albany.” He says, “I’d like to scramble some fighters to go tail him.” Spence replies that he will contact Otis Air Base about the situation, and tells Bueno, “I’ll talk to these guys over here and see what we can do.” Bueno then adds that Flight 11 is currently airborne, is about 40 miles south of Albany, and is visible only on primary radar. [Federal Aviation Administration, 4/19/2002; 9/11 Commission, 9/30/2003 ] Bueno also calls the air traffic control tower at Otis Air Base around this time, to alert it to Flight 11 and request military assistance (see (Between 8:30 a.m. and 8:40 a.m.) September 11, 2001). [Filson, 2003, pp. 47; Spencer, 2008, pp. 22] Whether he makes that call before or after he calls the Cape TRACON is unstated. Immediately after receiving the call from Bueno, Spence will call the Otis control tower to inform it of the situation, and he then calls the operations desk at Otis Air Base to let it know that it may be receiving orders (presumably from NEADS, NORAD’s Northeast Air Defense Sector) soon (see (8:36 a.m.-8:41) September 11, 2001). [9/11 Commission, 9/30/2003 ]Bueno Supposedly Violating Protocol - Bueno will say he decided to call the Cape TRACON based on his memory of a previous aircraft hijacking. [9/11 Commission, 9/22/2003 ] But according to the 9/11 Commission Report, by trying to get military assistance through the TRACON, the “Boston Center did not follow the protocol in seeking military assistance through the prescribed chain of command.” [9/11 Commission, 7/24/2004, pp. 20] Indeed, Bueno will tell the 9/11 Commission that he knows his call should instead be to NEADS, “but due to the urgency of the circumstance [he] called directly to the FAA contact point for Otis.” [9/11 Commission, 9/22/2003 ] And Spence will tell the Commission that arranging for fighters to be scrambled in response to a hijacking “is not the typical responsibility of an operations supervisor with the FAA,” like himself. He will also say that it is “unusual for the [air traffic control] centers to contact TRACON for information. Normally the FAA receives the call from the military for a scramble, but this time it went the other way around, and then the official order came back down from the military.” [9/11 Commission, 9/30/2003 ]Bueno Praised by Colleagues for Actions - However, according to the 9/11 Commission, “Bueno gets high marks” from the Boston Center personnel it interviews, “for instinctively calling FAA traffic approach personnel at the location where he knew the fighters to be—Otis [Air National Guard Base].” Even Colin Scoggins, the Boston Center’s military liaison, “who knew that the call had to go to NEADS, did not fault Bueno for trying to call the Air Force wing directly through other FAA personnel.” [9/11 Commission, 9/22/2003 ]

Apparently around 8:34 a.m., the FAA’s Boston Center attempts to contact an Atlantic City, New Jersey, military unit, to have it send fighters after Flight 11. However, the outcome of this call, and whether it is even answered, is unclear. [9/11 Commission, 7/24/2004, pp. 20] Atlantic City International Airport is the home of the 177th Fighter Wing of the New Jersey Air National Guard, which flies F-16 fighter jets. The 177th FW was part of NORAD’s alert force for many years, and kept two F-16s constantly on alert, ready to scramble when requested. But in October 1998, as a result of Pentagon cutbacks, it lost its scramble-ready status and began converting to a general-purpose F-16 mission (see May 19, 1997). [Bergen Record, 12/5/2003; GlobalSecurity (.org), 8/21/2005] The outcome of Boston Center’s attempt at contacting the Atlantic City unit is unclear. The 9/11 Commission will only state, “The center… tried to contact a former alert site in Atlantic City, unaware it had been phased out.” [9/11 Commission, 7/24/2004, pp. 20] NORAD’s Northeast Air Defense Sector (NEADS) will also try contacting the unit minutes later, but its call will not be answered (see (Between 8:40 a.m. and 8:46 a.m.) September 11, 2001). [Spencer, 2008, pp. 34] The Bergen Record will later comment that, with the removal of the Atlantic City fighters from NORAD’s alert mission, “the Pentagon left what seems to be a yawning gap in the midsection of its air defenses on the East Coast—a gap with New York City at the center.” [Bergen Record, 12/5/2003] Around this time, two F-16s from the 177th FW are away from base performing a training mission, and are just minutes from New York City, but the pilots are unaware of the unfolding crisis (see 8:46 a.m.-9:03 a.m. September 11, 2001).

Ray Scott, a manager at the American Airlines Southeastern Reservations Office in Cary, North Carolina, joins a phone call that his office has received from Betty Ong, a flight attendant on the hijacked Flight 11. [Federal Bureau of Investigation, 9/12/2001, pp. 64-65] Since 8:18 a.m., Ong has been on the phone with employees at the reservations office and has been describing to them the trouble on her plane (see 8:18 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 5] Scott was alerted to this, being told that an employee at the reservations office was handling an emergency phone call concerned with a hijacking. He went to the desk of reservation agent Vanessa Minter, one of the employees participating in the call, and now takes her place on the call. Scott Listens but Does Not Say Anything - After joining the call, Scott does not say anything to Ong. Instead, he just listens while Nydia Gonzalez, a supervisor at the reservations office, does the talking. Minter remains with Scott after he takes her place on the call. Scott will stay on the call with Ong until it ends. Scott Delayed before Joining Call - Minter will later recall that there was a delay before Scott was able to take over from her. She will say that after he arrived at her desk, she gave Scott her headset. However, he was unable to use it as it has an earpiece that was custom-made for Minter. Scott therefore had to go away and get his own headset, and is only able to join the call with Ong after returning to Minter’s desk with it. Accounts Conflict over When Scott Joins Call - The time at which Scott joins the call with Ong is unclear. Minter will estimate that she participates in the call for over 20 minutes before Scott takes over from her. This would mean Scott joins it sometime after 8:38 a.m. But Scott will estimate that he listens to about the last 10 minutes of the conversation with Ong. Since the call ends at around 8:44 a.m. or 8:45 a.m. (see (8:43 a.m.) September 11, 2001), this would mean he joins it at around 8:34 a.m., or shortly after. Scott will also say that he is listening to the call when Ong says a passenger who was in seat 10B is now in the cockpit. [Federal Bureau of Investigation, 9/12/2001, pp. 38-41; Federal Bureau of Investigation, 9/12/2001, pp. 64-65] This would mean he is already participating in the call by 8:35 a.m., when Ong provides this information (see 8:35 a.m.-8:36 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 12]

John Hartling. [Source: NBC News]By 8:34 a.m., Flight 11 has entered airspace managed by Boston Center air traffic controller John Hartling. [MSNBC, 9/11/2002; 9/11 Commission, 7/24/2004, pp. 19] Although Boston controller Pete Zalewski, who was managing Flight 11, concluded the plane was hijacked almost ten minutes earlier (see (8:25 a.m.) September 11, 2001), at the time the blip for Flight 11 appears on Hartling’s radar screen, Hartling is unaware that a hijacking is taking place. According to author Lynn Spencer, the reason is that “The concentration required for the job is so intense that controllers operate on a need-to-know basis. They don’t need to know what’s happening in other controllers’ sectors unless it might affect their own airspace, and distractions are rigorously kept to a minimum.” Tom Roberts, another Boston Center controller, has just been relieved from duty for a scheduled coffee break, and comes over to Hartling’s desk. Referring to Flight 11’s radar track, he tells Hartling, “This—this aircraft, we believe, is hijacked, and he’s last reported at 29,000 feet.” However, Hartling is incredulous. He will later recall that when Roberts says the plane is hijacked, “I didn’t believe him.” This is because “I didn’t think that that stuff would happen anymore, especially in this country.” Hartling continues tracking Flight 11 as it heads toward New York. Although its transponder has been turned off (see (Between 8:13 a.m. and 8:21 a.m.) September 11, 2001), he can tell that, at almost 600 mph, it is flying far faster than the 450 mph it should be moving at. [MSNBC, 9/11/2002; Spencer, 2008, pp. 22-24]

Colin Scoggins, the military liaison at the FAA’s Boston Center, claims he makes his first call to NORAD’s Northeast Air Defense Sector (NEADS) regarding Flight 11. He later recalls that he informs NEADS that the aircraft is “20 [miles] south of Albany, heading south at a high rate of speed, 600 knots.” [Griffin, 2007, pp. 43] Flight 11 was over Albany at 8:26 (see (8:26 a.m.-8:29 a.m.) September 11, 2001). [Federal Aviation Administration, 9/17/2001 ] At such a high speed, it would have reached 20 miles south of there around 8:28. However, Scoggins says he is quite certain he only arrives on the floor at Boston Center at around 8:35. He says that although he’d later tried to write up a chronology of events, he “couldn’t get a timeline that made any sense.” Furthermore, Scoggins claims that even before he’d arrived, Joseph Cooper, a Boston Center air traffic management specialist, had already phoned NEADS about the hijacking. [Griffin, 2007, pp. 43 and 335] The 9/11 Commission makes no mention of either call. It says “the first notification received by the military—at any level—that American 11 had been hijacked” is when Boston Center calls NEADS just before 8:38 a.m. (see (8:37 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20] However, a report by ABC News is more consistent with Scoggins’ claims, indicating that Boston Center contacts NEADS about the hijacking earlier, at around 8:31. [ABC News, 9/11/2002] (Boston Center also contacts the FAA’s Cape Cod facility at 8:34 and requests that it notify the military about Flight 11 (see 8:34 a.m. September 11, 2001). Apparently around the same time, it tries contacting a military unit at Atlantic City (see (8:34 a.m.) September 11, 2001).) Scoggins says he makes “about 40 phone calls to NEADS” in total on this day. [Griffin, 2007, pp. 43] NEADS Commander Robert Marr later comments that Scoggins “deserves a lot of credit because he was about the only one that was feeding us information. I don’t know exactly where he got it. But he was feeding us information as much as he could.” [Michael Bronner, 2006]

After being informed of the hijacking of Flight 11, Tim Spence, an operational supervisor at the FAA’s Cape Terminal Radar Approach Control (TRACON), calls the air traffic control tower and then the operations desk at Otis Air National Guard Base, to let them know that they might soon be receiving an order to scramble the base’s fighter jets. [9/11 Commission, 9/30/2003 ; 9/11 Commission, 2004] Daniel Bueno, a supervisor at the FAA’s Boston Center, has just called Spence at the Cape TRACON, which is located on Otis Air Base at Cape Cod, Massachusetts, and said he wanted fighter jets scrambled in response to Flight 11, which is a “possible hijack.” Spence told Bueno he would contact Otis Air Base and see what it could do to help (see 8:34 a.m. September 11, 2001). [Federal Aviation Administration, 4/19/2002; 9/11 Commission, 9/30/2003 ; 9/11 Commission, 8/26/2004, pp. 12]TRACON Supervisor Calls Otis Tower - Spence will later recall that in the five minutes following the call from Bueno, he makes “as many calls as possible.” He gets on the phone to the air traffic control tower at Otis Air Base, to notify the controllers there of the situation and receive information on who to call next, so as to facilitate Bueno’s request. Spence will recall that the Otis tower controller he speaks to gives him the telephone number for either Otis Air Base’s base operations or the supervisor of flying desk, which is the aviation section of the base operations desk. (He will be unable to recall exactly which number he is given.) Spence will say he “may have been given a second number” by the Otis tower controller, but he “does not recall directly.” TRACON Supervisor Calls Operations Desk - Spence then calls Otis Air Base’s operations desk. He will later be unable to remember who he speaks with there. But, he will recall, the “general discussion” he has with them is “an introduction of his position, the relay of the information of a hijack from [the FAA’s Boston Center], and a request for information on how to get a fighter scramble.” During the call, Spence acknowledges that he has no authority to authorize a fighter scramble, but he advises those at the base to prepare to receive a scramble order (presumably from NEADS, NORAD’s Northeast Air Defense Sector), since such an order is “probably on its way.” The person at the operations desk gives Spence the phone number for NEADS. Timing of Calls Unclear - The exact times when Spence calls the control tower and the operations desk at Otis Air Base are unclear. Spence will tell the 9/11 Commission that he makes the call to the control tower immediately after receiving the call from Bueno. [9/11 Commission, 9/30/2003 ] That call ended just before 8:36 a.m. [Federal Aviation Administration, 4/19/2002] However, according to the 9/11 Commission Report, “the first notification received by the military—at any level—that American 11 had been hijacked” is when the FAA’s Boston Center calls NEADS just before 8:38 a.m. (see (8:37 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20] If correct, that would indicate Spence calls the Otis tower at 8:38 a.m. or after. Bueno also called the Otis tower directly, to request military assistance in response to Flight 11 (see (Between 8:30 a.m. and 8:40 a.m.) September 11, 2001), and the tower controller subsequently contacts the base’s operations desk to alert it to the possible hijacking (see (Between 8:31 a.m. and 8:40 a.m.) September 11, 2001). [Filson, 2003, pp. 47; Spencer, 2008, pp. 22, 27-28] It is unclear whether the tower controller calls the operations desk before or after Spence calls it, although Spence will suggest to the 9/11 Commission that Otis Air Base “may have just received a call themselves regarding the situation” when he makes his calls, “but he is not sure.” [9/11 Commission, 9/30/2003 ]

Craig Marquis, a manager at the American Airlines System Operations Control (SOC) in Fort Worth, Texas, initiates actions to “lockout” Flight 11. This procedure, as the 9/11 Commission later describes, “acknowledges an emergency on the flight and isolates information so that the case can be managed by top leadership at the airlines in a way that protects information from being altered or released, and also protects the identities of the passengers and crew.” Within two minutes, American Airlines has completed the lockout. Marquis realized Flight 11 was an emergency situation almost immediately after 8:21 a.m., when he began receiving details of flight attendant Betty Ong’s phone call from it (see 8:21 a.m. September 11, 2001). Since “lockout” is a standard procedure for airlines in safety and security incidents, it is unclear why he did not initiate it sooner. [9/11 Commission, 7/24/2004, pp. 5; 9/11 Commission, 8/26/2004, pp. 12-13]

Tech. Sgt. Jeremy Powell. [Source: Scott A. Gwilt/ Rome Sentinel]The FAA’s Boston Center calls NORAD’s Northeast Air Defense Sector (NEADS) in Rome, NY, to alert it to the suspected hijacking of Flight 11. According to the 9/11 Commission, this is “the first notification received by the military—at any level—that American 11 had been hijacked.” [9/11 Commission, 7/24/2004, pp. 20; 9/11 Commission, 8/26/2004, pp. 13] The call is made by Joseph Cooper, an air traffic controller at the Boston Center, and answered by Jeremy Powell, a technical sergeant on the NEADS operations floor. [Vanity Fair, 8/1/2006; Spencer, 2008, pp. 25] Beginning the call, Cooper says: “Hi. Boston Center TMU [traffic management unit], we have a problem here. We have a hijacked aircraft headed towards New York, and we need you guys to, we need someone to scramble some F-16s or something up there, help us out.” Powell replies, “Is this real-world or exercise?” Cooper answers, “No, this is not an exercise, not a test.” [9/11 Commission, 7/24/2004, pp. 20] Shortly into the call, Powell passes the phone on to Lieutenant Colonel Dawne Deskins (see (8:38 a.m.) September 11, 2001). Deskins identifies herself to Cooper, and he tells her, “We have a hijacked aircraft and I need you to get some sort of fighters out here to help us out.” [Newhouse News Service, 1/25/2002; ABC News, 9/11/2002; Bamford, 2004, pp. 8; Spencer, 2008, pp. 26]Military Claims Call Goes against Procedure - The 1st Air Force’s official history of the response to the 9/11 attacks will later suggest that Boston Center is not following normal procedures when it makes this call to NEADS. It states: “If normal procedures had taken place… Powell probably wouldn’t have taken that phone call. Normally, the FAA would have contacted officials at the Pentagon’s National Military Command Center who would have contacted the North American Aerospace Defense Command. The secretary of defense would have had to approve the use of military assets to assist in a hijacking, always considered a law enforcement issue.” The only explanation it gives for this departure from protocol is that “nothing was normal on Sept. 11, 2001, and many say the traditional chain of command went by the wayside to get the job done.” [Filson, 2003, pp. 51]Accounts Conflict over Time of Call - There will be some conflict between different accounts, as to when this vital call from Boston Center to NEADS occurs. An ABC News documentary will indicate it is made as early as 8:31 a.m. [ABC News, 9/11/2002] Another ABC News report will state, “Shortly after 8:30 a.m., behind the scenes, word of a possible hijacking [reaches] various stations of NORAD.” [ABC News, 9/14/2002] NEADS logs indicate the call occurs at 8:40 a.m., and NORAD will report this as the time of the call in a press release on September 18, 2001. [Federal Aviation Administration, 9/17/2001 ; North American Aerospace Defense Command, 9/18/2001] The 8:40 time will be widely reported in the media prior to the 9/11 Commission’s 2004 report. [Associated Press, 8/21/2002; BBC, 9/1/2002; Newsday, 9/10/2002; CNN, 9/11/2002] But tape recordings of the NEADS operations floor that are referred to in the 9/11 Commission Report place the call at 8:37 and 52 seconds. [9/11 Commission, 7/24/2004, pp. 20; Vanity Fair, 8/1/2006] If the 8:37 a.m. time is correct, this would mean that air traffic controllers have failed to successfully notify the military until approximately 12 minutes after they became certain that Flight 11 had been hijacked (see (8:25 a.m.) September 11, 2001), 16 minutes after Flight 11’s transponder signal was lost (see (Between 8:13 a.m. and 8:21 a.m.) September 11, 2001), and 24 minutes after the plane’s pilots made their last radio contact (see 8:13 a.m. September 11, 2001). [9/11 Commission, 6/17/2004] At 8:34, the Boston Center tried contacting the military through the FAA’s Cape Cod facility, which is located on Otis Air National Guard Base, but was told that it needed to call NEADS (see 8:34 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20; Spencer, 2008, pp. 22]

Colin Scoggins, the military liaison at the FAA’s Boston Center, makes a brief phone call to NORAD’s Northeast Air Defense Sector (NEADS) to see if it has been able to find any further information about Flight 11. [Spencer, 2008, pp. 32-33] Boston Center has just alerted NEADS to the hijacking of Flight 11 (see (8:37 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20] Scoggins asks the ID technician who answers his call, “Have you identified the radar target for American 11?” The ID tech says they are still searching for it. Scoggins then tells her that Flight 11 is “50 miles south of Albany,” but, according to author Lynn Spencer, this information “won’t be of much help to NEADS Surveillance,” because “[t]heir monochromic displays aren’t even capable of showing the outline of states, much less those of cities like Albany or New York.” [Spencer, 2008, pp. 33] (However, despite this supposed inadequate capability, NEADS is reportedly able to spot Flight 11 shortly before it crashes into the World Trade Center (see 8:45 a.m.-8:46 a.m. September 11, 2001), locating its radar track “going down the Hudson Valley, straight in from the north toward New York.” [Filson, 2003, pp. 56] ) As NEADS has no new information to offer him, Scoggins quickly ends the call. According to Spencer’s account, this is the first time Scoggins calls NEADS this morning, after arriving at the Boston Center minutes earlier (see (8:25 a.m.-8:35 a.m.) September 11, 2001). [Spencer, 2008, pp. 33] But according to a description Scoggins gives to author David Ray Griffin in 2007, it appears that this is his second call, after an initial call at around 8:35 (see (8:35 a.m.) September 11, 2001). Scoggins will tell Griffin that he first called NEADS to inform it that Flight 11 was “20 [miles] south of Albany heading south at a high rate of speed, 600 knots,” and then he makes “another call at 50 [miles] south of Albany.” [Griffin, 2007, pp. 47]

At NORAD’s Northeast Air Defense Sector (NEADS), the technical sergeant who has been notified of the suspected hijacking of Flight 11 passes on this news to colleagues of his on the NEADS operations floor. [Spencer, 2008, pp. 25] The FAA’s Boston Center has just called NEADS to report “a hijacked aircraft headed towards New York,” and has requested that fighter jets be launched in response (see (8:37 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20] Tech. Sgt. Jeremy Powell, who answers this call, reportedly “bolts up and turns toward the ID section behind him on the ops floor.” He says, “We’ve got a hijack going on!” Master Sergeant Maureen Dooley, the leader of the ID section, mistakenly thinks this is part of the day’s training exercise (see (6:30 a.m.) September 11, 2001) and tells the other members of her team: “We have a hijack going on. Get your checklists. The exercise is on.” But Powell then clarifies: “No, you don’t understand. We have a no-shit hijack!” Sitting next to Dooley is Master Sergeant Joe McCain, the NEADS mission crew commander technician, who gets on the paging system and calls for the mission crew commander (MCC), Major Kevin Nasypany, to come to the operations floor immediately. Nasypany is in charge of the operations floor and needs to know if anything important is happening. He arrives moments later and learns of the hijacking. [Vanity Fair, 8/1/2006; Spencer, 2008, pp. 25-26 and 40]

Colonel Robert Marr, the battle commander at NORAD’s Northeast Air Defense Sector (NEADS), tries phoning Major General Larry Arnold, the commander of the Continental United States NORAD Region (CONR), to get authorization to scramble fighter jets in response to the hijacked Flight 11, but Arnold is in a teleconference, so Marr has to leave an urgent message requesting that Arnold call him back. [9/11 Commission, 7/24/2004, pp. 20; Spencer, 2008, pp. 31]Arnold Unavailable to Authorize Launching Fighters - Marr has just learned that the FAA is requesting NORAD assistance with a possible hijacking (see (8:38 a.m.) September 11, 2001), and has therefore ordered that fighter jets at Otis Air National Guard Base, Massachusetts, be placed on “battle stations,” with the pilots in the cockpits but the engines turned off (see (8:40 a.m.) September 11, 2001). [Filson, 2003, pp. 55; 9/11 Commission, 7/24/2004, pp. 20] He now tries calling Arnold at CONR headquarters, at Tyndall Air Force Base, Florida, to get authorization to scramble the fighters. However, Arnold is in a teleconference with other senior NORAD officials (see (8:30 a.m.-8:40 a.m.) September 11, 2001) and is therefore unavailable to talk to Marr. [Spencer, 2008, pp. 31]Marr Leaves Urgent Message for Arnold - Marr talks to Colonel Randy Morris, the assistant director of the CONR Regional Air Operations Center, and tells him about the possible hijacking. Morris replies that such an event “falls under law enforcement jurisdiction.” Marr says the FAA has requested military assistance with the hijacking and NEADS is “forward leaning” fighters from Otis Air Base, referring to his order to place Otis fighters on battle stations. [9/11 Commission, 2/3/2004 ] Marr leaves an urgent message for Arnold, stating that he is dealing with a hijacking and requesting that Arnold call him back. [9/11 Commission, 5/23/2003; Spencer, 2008, pp. 31] Arnold will be given Marr’s message after he leaves the teleconference (see (8:40 a.m.) September 11, 2001) and will promptly call Marr back (see (8:42 a.m.) September 11, 2001). [Filson, 2002; 9/11 Commission, 5/23/2003; 9/11 Commission, 2/3/2004 ] It is unclear why no one interrupts the teleconference to fetch Arnold to come and talk with Marr right away, or at least to immediately pass on Marr’s message. Unclear if Marr Needs Authorization to Scramble Fighters - It is also unclear why Marr seeks authorization from his superior before ordering that fighters be scrambled. According to Lieutenant Colonel Dawne Deskins, the aircraft control and warning officer at NEADS, the mission crew commander at NEADS—i.e. Major Kevin Nasypany—“is the lowest level rank that has the authority to give a scramble order.” However, Deskins will tell the 9/11 Commission: “[S]ince Colonel Marr was in the battle cab, it was his role. Since the decision involved a civilian aircraft, he had to be the one who made the decision.” [9/11 Commission, 10/30/2003 ] The 1st Air Force’s book about the 9/11 attacks will similarly state that the “sector commander” at NEADS, i.e. Marr, “would have authority to scramble the airplanes.” [Filson, 2003, pp. 50] But Arnold will say the reason the Otis fighters are placed on battle stations instead of being scrambled immediately is that aircraft hijacking is “considered a law enforcement issue.” The correct procedure, according to Arnold, is therefore that, if the FAA wants fighters scrambled, it should call the duty officer at the National Military Command Center at the Pentagon. He in turn contacts the NORAD operations center in Cheyenne Mountain, Colorado, to see if fighters are available. The operations center then seeks permission from someone representing the secretary of defense. Finally, “Once that is approved, then we scramble aircraft,” Arnold will say (see June 1, 2001). [Filson, 2002; Code One Magazine, 1/2002; 9/11 Commission, 5/23/2003]

National Guard troops stationed at NORAD’s Northeast Air Defense Sector (NEADS) in Rome, New York. [Source: Rome Sentinel]At NORAD’s Northeast Air Defense Sector (NEADS), a huddle of people is gathered around one of the radar scopes. NEADS Commander Robert Marr initially thinks this hubbub is due to the NORAD training exercise (presumably Vigilant Guardian) that is taking place on this day (see (6:30 a.m.) September 11, 2001). He will later recall: “I’ve seen many exercises… and as I saw that huddle I said, ‘There’s got to be something wrong, something is happening here.’ You usually see that whenever they find a track on the scope that looks unusual; it’s usually an indicator that something is getting ready to kick off.” [Filson, 2003, pp. 55] According to author Lynn Spencer, Marr thinks the day’s exercise “is kicking off with a lively, unexpected twist.… His bet is that his simulations team has started off the exercise by throwing out a ‘heart attack card’ to see how the troops respond to a first-aid call from a fellow soldier, testing their first responder training.” [Spencer, 2008, pp. 26] He sends Lieutenant Colonel Dawne Deskins, the regional mission crew commander for the exercise, to check out what is going on. [Filson, 2003, pp. 55] Deskins speaks briefly over the phone with the FAA’s Boston Center about the Flight 11 hijacking (see (8:37 a.m.) September 11, 2001). [Spencer, 2008, pp. 26] She then runs back to the “battle cab”—the glass-walled room that overlooks the NEADS operations floor—and speaks to Marr with urgency in her voice. [Filson, 2003, pp. 55] She tells him: “It’s a hijacking, and this is real life, not part of the exercise. And it appears that the plane is heading toward New York City.” Although Deskins has specifically stated, “not part of the exercise,” Marr reportedly thinks, “This is an interesting start to the exercise.” According to Spencer, he thinks “This ‘real-world’ mixed in with today’s simex [simulated exercise] will keep [his staff members] on their toes.” Regardless of whether the crisis is real or not, Marr decides to instruct that the two alert F-15s at Otis Air National Guard Base be ordered to battle stations (see (8:40 a.m.) September 11, 2001). [Spencer, 2008, pp. 26-27]

Major Kevin Nasypany. [Source: CBC]When the FAA’s Boston Center first contacts NORAD’s Northeast Air Defense Sector (NEADS) to notify it of the hijacking of Flight 11 (see (8:37 a.m.) September 11, 2001), personnel there initially mistake the hijacking for a simulation as part of an exercise. Lieutenant Colonel Dawne Deskins, mission crew chief for the Vigilant Guardian exercise currently taking place (see (6:30 a.m.) September 11, 2001), will later say that initially she and everybody else at NEADS think the call from Boston Center is part of Vigilant Guardian. [Newhouse News Service, 1/25/2002] Although most of the personnel on the NEADS operations floor have no idea what the day’s exercise is supposed to entail, most previous major NORAD exercises included a hijack scenario. [USA Today, 4/18/2004; Utica Observer-Dispatch, 8/5/2004] The day’s exercise is in fact scheduled to include a simulated hijacking later on. [Vanity Fair, 8/1/2006] Major Kevin Nasypany, the NEADS mission crew commander, had helped design the day’s exercise. Thinking the reported hijacking is part of it, he actually says out loud, “The hijack’s not supposed to be for another hour.” [Vanity Fair, 8/1/2006] In the ID section, at the back right corner of the NEADS operations floor, technicians Stacia Rountree, Shelley Watson, and Maureen Dooley react to the news. Dooley, the leader of the ID section, tells the other members of her team: “We have a hijack going on. Get your checklists. The exercise is on” (see (8:38 a.m.) September 11, 2001). Rountree asks, “Is that real-world?” Dooley confirms, “Real-world hijack.” Watson says, “Cool!” [Vanity Fair, 8/1/2006; Spencer, 2008, pp. 25] When NEADS Commander Robert Marr sees his personnel reacting to the news of the hijacking (see (8:38 a.m.) September 11, 2001), he reportedly thinks the day’s exercise “is kicking off with a lively, unexpected twist.” Even when a colleague informs him, “It’s a hijacking, and this is real life, not part of the exercise,” Marr thinks: “This is an interesting start to the exercise. This ‘real-world’ mixed in with today’s simex [simulated exercise] will keep [my staff members] on their toes.” [Spencer, 2008, pp. 26] Major General Larry Arnold, who is at Tyndall Air Force Base, Florida, also later says that when he first hears of the hijacking, in the minutes after NEADS is alerted to it, “The first thing that went through my mind was, is this part of the exercise? Is this some kind of a screw-up?” [ABC News, 9/11/2002; 9/11 Commission, 5/23/2003] According to author Lynn Spencer: “Even as NORAD’s commander for the continental United States, Arnold is not privy to everything concerning the exercise. The simex is meant to test commanders also, to make sure that their war machine is operating as it should.” [Spencer, 2008, pp. 38] At 8:43 a.m., Major James Fox, the leader of the NEADS weapons team, comments, “I’ve never seen so much real-world stuff happen during an exercise.” [Vanity Fair, 8/1/2006]

Lt. Col. Dawne Deskins. [Source: Newhouse News/ Peter Chen/ Landov]Members of staff at NORAD’s Northeast Air Defense Sector (NEADS) have difficulty locating Flight 11 and other aircraft on their radar screens. Lt. Col. Dawne Deskins of NEADS will say that when the FAA first calls and reports the first hijacking (see (8:37 a.m.) September 11, 2001), “He [FAA] gave me the latitude and longitude of that track… [but] there was nothing there.” [Fox News, 9/8/2002] Colin Scoggins, the military liaison at the FAA’s Boston Center, later recalls: “I was giving NEADS accurate location information on at least five instances where AA 11 was, yet they could never identify him.… I originally gave them an F/R/D, which is a fix/radial/distance from a known location; they could not identify the target. They requested latitude/longitudes, which I gave them; they still could not identify the AA 11.… I gave them 20 [miles] south of Albany heading south at a high rate of speed, 600 knots, then another call at 50 south of Albany.” [Griffin, 2007, pp. 47] Master Sergeant Kevin Foster and Staff Sergeant Mark Rose, also working at NEADS this morning, later complain about their inability to locate the hijacked planes. After being informed of the first hijacking, reportedly: “As they had practiced countless times before, the NEADS team quickly began searching their [radar] screens for the plane. Because they had been informed its transponder was off, they knew to look for a tiny dash instead of the usual dot. But radar systems also use such lines to indicate weather patterns, so NEADS personnel began urgently clicking their computer cursors on each stray line to see if information indicating an aircraft would appear.” Yet, after receiving further calls indicating more hijackings, “the inability to find the hijacked planes on the radar, despite their best efforts, was difficult.” According to Foster, “We were trying to find the tracks, and not being able to was very frustrating.” [Utica Observer-Dispatch, 8/5/2004] NEADS Staff Sergeant Larry Thornton will recall: “Once we were called by the FAA, we could find split-second hits on what we thought we were looking for. But the area was so congested and it was incredibly difficult to find. We were looking for little dash marks in a pile of clutter and a pile of aircraft on a two-dimensional scope.” Each fluorescent green pulsating dot on their radar scopes represents an airplane, and there are thousands currently airborne, especially over the busy northeast US. [Filson, 2003, pp. 56]

Following a call from the FAA’s Boston Center to the the FAA’s Cape Cod facility reporting the possible hijacking of Flight 11 (see 8:34 a.m. September 11, 2001), and a subsequent call from the Cape Cod facility to Otis Air National Guard Base (see (8:36 a.m.-8:41) September 11, 2001), Lt. Col. Jon Treacy, commander of the 101st Fighter Squadron at Otis, phones NORAD’s Northeast Air Defense Sector (NEADS) to report the FAA’s request for help and get authorization to launch fighters. By now though, the FAA has already gotten through to NEADS itself, and reported the hijacking (see (8:37 a.m.) September 11, 2001). [Filson, 2003, pp. 50]

The talkback button on Flight 11, which has been periodically activated since around 8:14 a.m., stops around this time. Some have suggested that this indicates that the hijackers replace pilot John Ogonowski at this time. [Christian Science Monitor, 9/13/2001; MSNBC, 9/15/2001]

Don Arias [Source: US Air Force]Lt. Col. Dawne Deskins of NEADS twice calls Major Don Arias, the 1st Air Force and Continental United States NORAD Region public affairs officer, who is at the 1st Air Force public affairs office at Tyndall Air Force, Florida. She first calls him after NEADS is informed of the hijacking of Flight 11 (see (8:37 a.m.) September 11, 2001). She says that NEADS has “a hijacked plane—no, not the simulation—likely heading for JFK [International Airport in New York City].” [Newhouse News Service, 1/25/2002] The “simulation” refers to a NORAD air defense exercise, presumably Vigilant Guardian, that Arias is involved in. Deskins informs him that fighters are going to be launched after the aircraft. Arias then starts working on a public statement about the incident, but soon after sees the smoking WTC tower on CNN. He says that he thinks, “Wow, I bet that’s the hijacked plane.” [Florida State Times, 11/2001; Airman, 9/2002; Filson, 2003, pp. 122] Minutes after the crash, Deskins calls Arias again and tells him, “We think the aircraft that just hit the World Trade Center was American Airlines Flight 11.” According to Deskins, Arias responds, “Oh, God. My brother works in the World Trade Center.” [Newhouse News Service, 1/25/2002; ABC News, 9/11/2002; Bamford, 2004, pp. 13-14] Arias will quickly contact his brother (see (8:53 a.m.) September 11, 2001).

Technicians at NORAD’s Northeast Air Defense Sector (NEADS) try frantically to locate Flight 11 on their radar scopes, but are supposedly hindered by their outdated equipment. [Spencer, 2008, pp. 31-32] NEADS has just been alerted to the hijacking of Flight 11 (see (8:37 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20] Its technicians realize they need to find the location of the hijacked plane quickly, so that the weapons team will be able to pass this information on to any fighter jets that are launched after it. Locating Flight 11 Is a 'Grueling Process' - Author Lynn Spencer will later explain: “To identify American 11, the surveillance and ID techs must go through a grueling process. Their radar scopes are filled with hundreds of radar returns not just from aircraft but from weather systems, ground interference, and what’s called anomalous propagation—false returns caused by conditions in the atmosphere, or by such obstructions as flocks of birds. The technicians must first determine which radar data on their screens is for aircraft, which they do by monitoring its movement, which is distinctive for planes. The technician must observe for at least 36 seconds to a minute just to confirm that a blip is in fact an aircraft track. The tech must attach what’s called a tactical display number to it, which tells the computer to start tracking and identifying the target. If the target is in fact a plane, then over a period of 12-20 seconds, the computer will start to generate information on the track: heading, speed, altitude, latitude, longitude, and the identifying information being transmitted by the transponder.” However, Flight 11’s transponder has been switched off (see (Between 8:13 a.m. and 8:21 a.m.) September 11, 2001). Therefore, “With the hundreds of pieces of radar data filling their screens, and little information as to the location of the flight,” the task of locating it “is daunting.” Radar Equipment Supposedly Unsuitable - Spencer will suggest that trying to locate Flight 11 is made more difficult because the radar equipment at NEADS is outdated and unsuited to the task at hand. She writes: “[T]he NEADS radar equipment is different from that used by air traffic controllers. It’s much older, developed in the 1970s and brought into use by NEADS in the early 1980s. The system was designed to monitor the shoreline for incoming high-altitude threats: missiles coming from across the ocean. Slow and cumbersome, and not nearly as user friendly as more modern equipment, the NEADS monochromic radar displays are not designed to take internal FAA radar data or to identify radar tracks originating from inside the United States. The system offers little, if any, such low-level coverage over the country.” [Spencer, 2008, pp. 31-32] Several of the NEADS personnel will later complain of their inability to locate Flight 11 on their scopes (see Shortly After 8:37 a.m. September 11, 2001). But Master Sergeant Joe McCain, the mission crew commander technician at NEADS, believes he has located Flight 11 on the radar screen just before it crashes into the World Trade Center (see 8:45 a.m.-8:46 a.m. September 11, 2001).

While flying south along the Hudson River, Flight 11 passes almost directly over the Indian Point nuclear power plant in Buchanan, NY, about 30 miles north of New York City. [New York Times, 4/4/2002; Bergen Record, 4/7/2002] The New Yorker will later comment, “An attack on a nuclear power plant would seem to fulfill, almost perfectly, al-Qaeda’s objective of using America’s technology against it,” and the New York Times will report, “Everyone within at least a 50-mile radius would be in danger if something terrible happened at Indian Point. That 50-mile radius contains more than 7 percent of the entire population of the United States—20 million people.” [New York Times, 4/4/2002; New Yorker, 2/24/2003] Mohamed Atta supposedly earlier considered targeting a nuclear facility on 9/11, but the other suicide pilots did not like the idea (see Between July 9 and July 16, 2001).

Colin Scoggins, the military liaison at the FAA’s Boston Center, calls the FAA’s New York Center but is quickly cut off when the air traffic controller who answers says the center is busy dealing with a hijacking. According to author Lynn Spencer, Scoggins “calls New York Center to notify them that American 11 appears to be descending toward New York, most likely to land at JFK” International Airport. But the controller who takes the call snaps at him: “We’re too busy to talk. We’re working a hijack,” and then hangs up. According to Spencer, the New York Center controller is referring to Flight 175, but “Scoggins just figures that he’s talking about American 11. He has no idea that a second airliner is in crisis.” However, the timing of this call is unclear. If it is made while Flight 11 is descending toward New York, this would mean it occurs in the minutes before 8:46, when Flight 11 crashes (see 8:46 a.m. September 11, 2001). But in Spencer’s account, the call is made just after New York Center controller Dave Bottiglia notices that Flight 175’s transponder code has changed and he calls out to another controller, “I can’t get a hold of UAL 175 at all right now and I don’t know where he went to” (see 8:51 a.m.-8:53 a.m. September 11, 2001). [Spencer, 2008, pp. 48-49] The transcript of radio communications between the New York Center and Flight 175 shows that this would mean Scoggins’s call occurs around 8:53 a.m.-8:54 a.m., about seven minutes after Flight 11 crashes. [New York Times, 10/16/2001]

Nancy Wyatt, a manager at the American Airlines flight services office at Logan International Airport in Boston, talks on the phone with an employee at the American Airlines System Operations Control (SOC) center, and passes on to them information that is being provided by a flight attendant on the hijacked Flight 11, but the SOC employee advises Wyatt to keep quiet about the hijacking. [American Airlines, 9/11/2001, pp. 34-41; 9/11 Commission, 2004, pp. 4; 9/11 Commission, 8/26/2004, pp. 14; Rutgers Law Review, 9/7/2011, pp. 14 ] Amy Sweeney, a flight attendant on Flight 11, called the flight services office at 8:32 a.m., and has since then been providing details of the trouble on her plane to Michael Woodward, an American Airlines flight services manager at Logan Airport (see (8:32 a.m.-8:44 a.m.) September 11, 2001). [9/11 Commission, 8/26/2004, pp. 11]Wyatt Passes on Details of Call in Real Time - Wyatt, who, like Woodward, is an American Airlines flight services manager, calls the American Airlines SOC in Fort Worth, Texas, at 8:40 a.m. Her call is answered by Ray Howland. [Federal Bureau of Investigation, 9/15/2001, pp. 2-4; 9/11 Commission, 2004, pp. 4; 9/11 Commission, 8/26/2004, pp. 14] During the call, Wyatt is able to pass on information to Howland in real time, because she is standing next to Woodward and so is hearing his side of the conversation with Sweeney, and she is also able to read the notes he is taking, based on what Sweeney tells him. [9/11 Commission, 1/25/2004 ]Wyatt Unclear about Name of Flight Attendant - Wyatt is unclear about the identity of the flight attendant Woodward is talking to. At the start of the call with Howland, she says, “We’ve got the flight attendants on the line here.” A couple of minutes later, she says, “We’ve got… Betty Ong, the purser, on the line.” [American Airlines, 9/11/2001, pp. 34-41] However, Ong is currently on the phone with the American Airlines Southeastern Reservations Office in North Carolina (see 8:18 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 8] Finally, another couple of minutes later and after checking with Woodward, Wyatt tells Howland, “Amy Sweeney is on the phone.” Wyatt Passes on Hijackers' Seat Numbers - Based on Sweeney’s information, Wyatt says that Flight 11 “is in a rapid descent.” She tells Howland that the hijackers were in seats 9D, 9G, and 10B, and she says one of them “speaks no English.” She also reports, several minutes into the call, that the hijackers are “in the cockpit.” Wyatt tells Howland that two flight attendants, Karen Martin and Barbara Arestegui, have been stabbed. [American Airlines, 9/11/2001, pp. 34-41] Referring to passenger Daniel Lewin, who was attacked by one of the hijackers (see (8:20 a.m.) September 11, 2001), she says: “There is severe bleeding. There is a slashed throat.” She subsequently says, “There is a passenger also injured.” [American Airlines, 9/11/2001, pp. 34-41; WBUR, 9/8/2011]Airline Wants Information Withheld from Plane's Crew - During the call, Howland tells Wyatt that the SOC wants some information to be withheld from Sweeney and the other crew members on Flight 11. After Wyatt says the flight attendants on Flight 11 “are concerned” because they “don’t know what’s going on in the cockpit,” Howland replies that the SOC is “trying to get in contact with the cockpit,” but then says, “We don’t really want to tell [Sweeney] that.” Wyatt confirms: “Okay, don’t. Okay, okay. Got it.” And when Wyatt later asks: “Do we know where that plane is going to right now?” Howland replies: “We don’t know.… [I]t looks like it’s going to JFK” International Airport in New York, but he then says: “I mean, we don’t really want to give a whole lot of information to that flight. Okay?” Wyatt confirms: “Okay, we’re not. We’re not giving them that information to that flight.” Airline Employees Told to Keep Quiet about Hijacking - Wyatt and Howland also want American Airlines employees on the ground to keep quiet about the hijacking. At about 8:46 a.m., while she is still on the phone with Howland, Wyatt says to a colleague of hers: “Evelyn, don’t mention this to anyone. Me, you, Beth. Just the five of us. Okay?” [American Airlines, 9/11/2001, pp. 34-41] (“Evelyn” and “Beth” are Evelyn Nunez and Elizabeth Williams, two American Airlines employees at Logan Airport. [Federal Bureau of Investigation, 9/11/2001, pp. 57-58; Federal Bureau of Investigation, 9/13/2001, pp. 3-4; 9/11 Commission, 1/25/2004 ] ) Near the end of her call with Howland, Wyatt asks, “What do you want us to do as far as just keeping our mouths shut and not… ?” Howland answers simply, “That’s basically it.” [American Airlines, 9/11/2001, pp. 34-41] Wyatt notifies Howland when the call from Sweeney gets disconnected, at around 8:45 a.m. (see (8:44 a.m.) September 11, 2001). [9/11 Commission, 8/26/2004, pp. 14] Her call with Howland ends at 8:48 a.m. [9/11 Commission, 2004, pp. 4]

Major General Larry Arnold, the commander of the Continental United States NORAD Region (CONR), learns of the possible hijacking of Flight 11 after leaving a video teleconference, but initially thinks the reported hijacking is part of a NORAD training exercise. [Filson, 2002; Code One Magazine, 1/2002] Arnold, who is at CONR headquarters, at Tyndall Air Force Base, Florida, has been in the video teleconferencing room, participating in a teleconference with other senior NORAD officials (see (8:30 a.m.-8:40 a.m.) September 11, 2001). [9/11 Commission, 2/2/2004 ; Spencer, 2008, pp. 31] Colonel Robert Marr, the battle commander at NORAD’s Northeast Air Defense Sector (NEADS), recently tried phoning Arnold to get authorization to scramble fighter jets in response to the hijacked Flight 11, but no one at CONR interrupted the teleconference to fetch Arnold, and so Marr left an urgent message for the CONR commander (see (8:38 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20; Spencer, 2008, pp. 31]Note Informs Arnold of Hijacking - Arnold is now in the video teleconferencing room with Robert Del Toro, an intelligence officer with the 1st Air Force, discussing the just-concluded teleconference, when his executive officer, Kelley Duckett, hands him a note with Marr’s message on it. The note says the FAA’s Boston Center is reporting a hijacking and requesting assistance with it, and asks that Arnold phone Marr back immediately. [Filson, 2002; 9/11 Commission, 5/23/2003; 9/11 Commission, 2/2/2004 ; 9/11 Commission, 2/3/2004 ]Arnold Thinks Hijacking Is 'Part of the Exercise' - NORAD is currently in the middle of a major training exercise called Vigilant Guardian. [Code One Magazine, 1/2002; Arkin, 2005, pp. 545] Arnold will later say that, as a result, when he learns of the possible hijacking: “The first thing that went through my mind was: ‘Is this part of the exercise? Is this some kind of a screw-up?’” [ABC News, 9/11/2002] According to author Lynn Spencer, “Even as NORAD’s commander for the continental United States, Arnold is not privy to everything concerning the exercise.” The exercise “is meant to test commanders also, to make sure that their war machine is operating as it should.” Arnold Told Hijacking Is 'Real-World' - Since a simulated hijacking is scheduled as part of the day’s exercise (see (9:40 a.m.) September 11, 2001), Arnold asks Duckett, “Is this part of the exercise?” Duckett replies that the hijacking is real-world. [Spencer, 2008, pp. 38] Arnold will say that “understanding this is real-world is obviously important, so I rushed downstairs to our battle staff position.” [Filson, 2002] It occurs to Arnold that it has been many years since NORAD handled a hijacking (see February 11, 1993). He is relieved that, “because we were in the middle of an exercise,” he recently reviewed the protocol for what to do in response to a hijacking, and so “we were pretty well familiar with those procedures.” [9/11 Commission, 5/23/2003; Spencer, 2008, pp. 38] Arnold will promptly phone Marr and instruct him to go ahead and scramble fighters in response to the hijacking (see (8:42 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20; Spencer, 2008, pp. 38-39]

At the FAA’s Herndon Command Center, the national operations manager, Ben Sliney, learns more details of the hijacking of Flight 11, and becomes involved with the emergency response to it. [Spencer, 2008, pp. 21] A supervisor at the Command Center informed Sliney of the suspected hijacking at just before 8:30 (see 8:28 a.m. September 11, 2001). Soon after, the supervisor interrupted a meeting Sliney was in, to tell him American Airlines had called to report the deteriorating situation on Flight 11 (see 8:30 a.m.-8:40 a.m. September 11, 2001). Sliney Receives More Details - Sliney heads to the center’s operations floor, where the supervisor gives him further details of the call from American Airlines, including information about flight attendant Betty Ong’s phone call from Flight 11 (see 8:19 a.m. September 11, 2001). The supervisor says the plane’s transponder has been switched off (see (Between 8:13 a.m. and 8:21 a.m.) September 11, 2001), which means no flight data is showing on the screens of air traffic controllers, and the latest information from the FAA’s Boston Center is that Flight 11 has turned south, and is now 35 miles north of New York City. On one of the large screens at the front of the Command Center that shows flight trajectories, Sliney can see that the track for Flight 11 is in “ghost.” This means that, because no transponder data is being received, the computer is displaying track information based on previously stored track data. Sliney Seeks Information, Requests Teleconference - Sliney instructs his staff to contact facilities along the path the flight appears to be on, to find if anyone is in contact with it or tracking it. [Spencer, 2008, pp. 1 and 19-21] He will later recall, “I figured we’d try to get the people on the ground, the towers in the area, the police departments, anyone we could get to give us information on where this flight was.” [Canadian Broadcasting Corporation, 9/10/2006] Sliney then requests a teleconference between the FAA’s Boston Center, New York Center, and FAA headquarters in Washington, so they can share information about the flight in real time. [Spencer, 2008, pp. 21] The Command Center has already initiated a teleconference between the Boston, New York, and Cleveland Centers, immediately after it was notified of the suspected Flight 11 hijacking. [9/11 Commission, 8/26/2004, pp. 11] However, Sliney apparently does not request military assistance. According to author Lynn Spencer, “The higher echelons at headquarters in Washington will make the determination as to the necessity of military assistance in dealing with the hijacking.” [Spencer, 2008, pp. 21]

Flight 175 passes from the airspace of the FAA’s Boston Center to the airspace of the New York Center, which is in Ronkonkoma, New York. [9/11 Commission, 8/26/2004, pp. 20] New York Center air traffic controller Dave Bottiglia takes over monitoring the flight from Boston Center controller John Hartling (see (8:34 a.m.) September 11, 2001). Flight 175 waits nearly 45 seconds to check in with Bottiglia. According to author Lynn Spencer, this is “rather long, and Bottiglia is just about to call the plane.” But then Captain Victor Saracini, the pilot of Flight 175, makes radio contact, saying, “New York, United 175 heavy.” [Gregor, 12/21/2001 ; Spencer, 2008, pp. 36]

Craig Marquis, the manager on duty at the American Airlines System Operations Control (SOC) center in Fort Worth, Texas, instructs Bill Halleck, an air traffic control specialist at the SOC, to tell FAA air traffic controllers to treat Flight 11 as an emergency. [American Airlines, 9/11/2001, pp. 7-19; 9/11 Commission, 11/19/2003 ; 9/11 Commission, 8/26/2004, pp. 14] Halleck contacted the FAA’s Boston Center at 8:29 a.m. to inquire about Flight 11 (see 8:29 a.m. September 11, 2001), and at 8:33 a.m. he called Marquis and passed on what he had just learned from the Boston Center about the crisis with the aircraft (see 8:33 a.m. September 11, 2001). That information, according to the 9/11 Commission, led American Airlines to suspect that Flight 11 had been hijacked. [9/11 Commission, 8/26/2004, pp. 11-12] Marquis now instructs Halleck, “Tell [air traffic control] to handle this as an emergency.” According to a 9/11 Commission memorandum, “At this point, Marquis was just confirming it was a hijack and he wanted to make sure Halleck was communicating the emergency to the [air traffic control] system.” Halleck answers that FAA controllers are treating Flight 11 as a hijacking, saying, “They have in there, it’s been hijacked.” Marquis replies: “It is. Okay.” Halleck adds that FAA controllers “don’t know what his altitude is… they think he’s descending. They think he’s headed toward Kennedy [JFK International Airport in New York]… they’re moving everybody out of the way.” Referring to Betty Ong, a flight attendant on Flight 11, Marquis tells Halleck, “I’m talking to the flight attendant in the back of the plane and she says the plane is descending.” [American Airlines, 9/11/2001, pp. 7-19; American Airlines, 1/15/2002; 9/11 Commission, 11/19/2003 ]

One of the ID technicians at NORAD’s Northeast Air Defense Sector (NEADS) calls the FAA’s Boston Center, and learns that there have been “threats in the cockpit” of Flight 11. The communications team at NEADS is currently trying to quickly find out all they can about the hijacked plane, such as its flight number, tail number, and where it is. ID tech Shelley Watson calls the management desk at the Boston Center, which had alerted NEADS to the hijacking minutes earlier (see (8:37 a.m.) September 11, 2001), wanting to make sure she has all the information that is available on Flight 11. Her call is answered by Boston Center’s military liaison, Colin Scoggins. Scoggins tells Watson: “He’s being hijacked. The pilot’s having a hard time talking to the… I mean, we don’t know. We don’t know where he’s goin’. He’s heading towards Kennedy [International Airport in New York City]. He’s… 35 miles north of Kennedy now at 367 knots. We have no idea where he’s goin’ or what his intentions are.” Scoggins says, “I guess there’s been some threats in the cockpit,” and adds, “We’ll call you right back as soon as we know more info.” Master Sergeant Maureen Dooley is standing over Watson, relaying any pertinent information she hears to Major Kevin Nasypany. She calls to him, “Okay, he said threat to the cockpit!” [Vanity Fair, 8/1/2006; Spencer, 2008, pp. 34]

The emblem of the 177th Fighter Wing. [Source: United States Air Force]Colin Scoggins, the military liaison at the FAA’s Boston Center, calls NORAD’s Northeast Air Defense Sector (NEADS) and suggests that it contact a military unit at Atlantic City, New Jersey. However, when NEADS tries phoning the unit, the call is not answered. Scoggins Notices Otis Jets Not Yet Launched - Scoggins had called NEADS at around 8:38 a.m., regarding the hijacked Flight 11 (see (8:38 a.m.) September 11, 2001). A few minutes after this, he notices that fighter jets have not yet launched from Otis Air National Guard Base, at Cape Cod, Massachusetts, and calls NEADS again. He suggests that it should try to get jets launched from Atlantic City. [Spencer, 2008, pp. 32-34] Atlantic City International Airport is the home of the 177th Fighter Wing of the New Jersey Air National Guard. [GlobalSecurity (.org), 8/21/2005] As author Lynn Spencer will describe, Scoggins “knows that Atlantic City is no longer an alert facility, but he also knows that they launch F-16s for training flights every morning at nine. He figures that the pilots are probably already in their planes and ready to go. They’re unarmed, but they’re a lot closer to New York City than the Otis fighters on Cape Cod, and the military serves only a monitoring purpose in hijacking anyway.” [Spencer, 2008, pp. 33-34] Two F-16s from the 177th Fighter Wing are in fact already airborne and performing their training mission, and are just a few minutes flying time from New York City (see 8:46 a.m.-9:03 a.m. September 11, 2001). [Bergen Record, 12/5/2003] Scoggins will later recount: “I requested that we take from Atlantic City very early in the [morning], not launch from the ground but those already airborne in Warning Area 107 [a training area] if they were there, which I believe they were.” He will add that the 177th Fighter Wing does not “have an intercept mission; it was taken away a long time ago. [But] NEADS could have called them and asked them to cancel their [training] mission and divert.” [Griffin, 2007]NEADS Tries Unsuccessfully to Contact Unit - The NEADS technician who takes Scoggins’s call follows his advice, and tries to call the unit at Atlantic City. He calls the only number he has for it, which is the number NEADS had previously called when it wanted to scramble 177th Fighter Wing F-16s until 1998, back when they were part of NORAD’s alert force. The number connects the technician directly to the highly secured command post. However, no one answers the phone. According to Spencer: “[T]hese days, the command post is more of a highly secured storage area, opened just once a month for drill weekends. The phone rings and rings.” [Spencer, 2008, pp. 34] The FAA’s Boston Center also attempted to call the Atlantic City unit, apparently several minutes earlier (see (8:34 a.m.) September 11, 2001). The outcome of that call is unstated. [9/11 Commission, 7/24/2004, pp. 20]

American Airlines’ System Operations Command Center. [Source: American Airlines]American Airlines managers activate the System Operations Command Center (SOCC) in order to manage the company’s response to the terrorist attacks. [9/11 Commission, 1/27/2004; 9/11 Commission, 8/26/2004, pp. 12] The SOCC is a dedicated crisis response facility located on the floor above, and overlooking, the American Airlines System Operations Control (SOC) center in Fort Worth, Texas. [9/11 Commission, 11/19/2003 ; 9/11 Commission, 1/27/2004] Activating the command center allows the airline to isolate an event and gather together the people needed to manage it. [9/11 Commission, 1/7/2004 ] The SOCC is activated in emergencies, such as major accidents and hijackings, during which the airline’s top operations officials assemble there. Craig Parfitt, the managing director of dispatch operations, and Joseph Bertapelle, the manager of SOC operations coordination/air traffic systems, will serve as its directors today. [USA Today, 8/12/2002; 9/11 Commission, 11/19/2003 ]Accounts Unclear over When SOCC Is Activated - The exact time when the SOCC is activated is unclear. Gerard Arpey, American Airlines’ executive vice president of operations, will tell the 9/11 Commission that when he arrives at the SOC, between around 8:35 a.m. and 8:40 a.m. (see (8:30 a.m.-8:40 a.m.) September 11, 2001), he sees that Parfitt, Bertapelle, and Kyle Phelps, the manager of administration for the SOC, are setting up the SOCC. By around 8:45 a.m. or 8:50 a.m., according to Arpey, the command center is filling up with people. [9/11 Commission, 1/8/2004 ; 9/11 Commission, 1/27/2004] But Parfitt will indicate that the SOCC is activated slightly later. He will tell the 9/11 Commission that it is being set up after the airline’s 8:45 a.m. conference call (see 8:45 a.m. September 11, 2001) and that senior managers, including himself, arrive there at around 8:55 a.m. Craig Marquis, the manager on duty at the SOC, will say that at about 8:50 a.m., he looks up and notices activity in the SOCC. [9/11 Commission, 11/19/2003 ] The SOC manager is the individual responsible for activating the SOCC, according to a 9/11 Commission memorandum. However, it is unclear whether Marquis makes the decision to activate the command center on this occasion. [9/11 Commission, 11/19/2003 ]Airline's Key Decisions Made in the SOCC - The SOCC will be primarily responsible for dealing with the crisis. [9/11 Commission, 4/26/2004 ] The key decisions on the airline’s immediate response to the hijackings will be made there. American Airlines employees in the command center will provide assistance to the FBI and other law enforcement agencies involved in investigating the attacks. The SOCC will remain open 24 hours a day for the next two weeks. [9/11 Commission, 11/19/2003 ; 9/11 Commission, 1/27/2004]

Major Daniel Nash. [Source: Cape Cod Times]Major Daniel Nash (codenamed Nasty) and Lieutenant Colonel Timothy Duffy (codenamed Duff) are the two F-15 pilots who would scramble after Flight 11. Apparently, they get several informal calls warning to get ready. According to Nash, at this time, a colleague at the Otis Air National Guard Base tells him that a flight out of Boston has been hijacked, and that he should be on alert. [Cape Cod Times, 8/21/2002] NEADS senior technician Jeremy Powell (informed about the hijacking at 8:37 a.m.), says that he telephones Otis Air National Guard Base soon thereafter to tell it to upgrade its “readiness posture.” [Newhouse News Service, 1/25/2002] Boston flight control had tried calling the Otis base directly at 8:34 a.m., although the result of that call remains unclear. Duffy recalls being warned: “I was just standing up by the ops desk and I was told I had a phone call. I asked who it was and they said the [Boston] tower calling and something about a hijacking. It was Flight American 11, a 767, out of Boston going to California. At the time we ran in and got suited up.” [Aviation Week and Space Technology, 6/3/2002; Cape Cod Times, 8/21/2002; BBC, 9/1/2002] At NEADS, the mission crew commander Major Kevin Nasypany orders his Weapons Team, which controls the fighters, to put the Otis planes on “battle stations.” This means the two “alert” pilots are “jolted into action by a piercing ‘battle horn.’ They run to their jets, climb up, strap in, and do everything they need to do to get ready to fly short of starting the engines.” [Vanity Fair, 8/1/2006] NEADS Commander Robert Marr is also reported as having ordered the Otis pilots to battle stations. [Filson, 2003, pp. 55; 9/11 Commission, 7/24/2004, pp. 20] Duffy confirms, “Halfway to the jets, we got ‘battle stations’… which means to get ready for action.” [Aviation Week and Space Technology, 6/3/2002] The actual scramble order does not come until the pilots are already waiting in the fighters: “We went out, we hopped in the jets and we were ready to go—standby for a scramble order if we were going to get one.” [BBC, 9/1/2002] Duffy continues, “I briefed Nasty on the information I had about the American Airlines Flight. About four-five minutes later, we got the scramble order and took off.” [Aviation Week and Space Technology, 6/3/2002] However, the official notification to scramble these fighters does not come until 8:46 a.m. The six-minute (or more) delay between unofficial and official notification has not been explained.

Craig Marquis, the manager on duty at the American Airlines System Operations Control (SOC) center in Texas, tells Nydia Gonzalez, a supervisor at the American Airlines Southeastern Reservations Office in North Carolina, that FAA air traffic controllers are handling Flight 11 as a “confirmed hijacking.” [American Airlines, 9/11/2001, pp. 7-19] Gonzalez is one of several employees at the reservations office who are on the phone with Betty Ong, a flight attendant on Flight 11 who has been describing to them the trouble on her plane. Gonzalez has been relaying the information Ong provides to Marquis. [9/11 Commission, 11/19/2003 ; 9/11 Commission, 8/26/2004, pp. 8-9] She asks him, “What’s going on on your end, Craig?” [American Airlines, 9/11/2001, pp. 7-19] Marquis has just been told by a colleague at the SOC that FAA controllers are treating Flight 11 as a hijacking (see 8:40 a.m. September 11, 2001). [9/11 Commission, 11/19/2003 ; 9/11 Commission, 7/24/2004, pp. 6] He therefore replies: “We contacted air traffic control. They are gonna handle this as a confirmed hijacking. So they’re moving all the traffic out of this aircraft’s way.” He says that Flight 11 has its “transponder off, so we don’t have a definitive altitude for him.” Marquis adds that FAA controllers “seem to think that they have [Flight 11] on a primary radar. They seem to think that he is descending.” [American Airlines, 9/11/2001, pp. 7-19]

Victor Saracini. [Source: Family photo]Just after Flight 175 enters the airspace of the FAA’s New York Center (see 8:40 a.m. September 11, 2001), its pilot reports to the air traffic controller now managing the flight a suspicious transmission he had heard on departing Boston’s Logan Airport. The pilot, Captain Victor Saracini, tells the controller, Dave Bottiglia: “We figured we’d wait to go to your center. Ah, we heard a suspicious transmission on our departure out of Boston, ah, with someone, ah, it sounded like someone keyed the mikes and said, ah, ‘Everyone, ah, stay in your seats.’” [New York Times, 10/16/2001; 9/11 Commission, 7/24/2004, pp. 21; Spencer, 2008, pp. 36] Saracini is presumably referring to one of the three radio transmissions from Flight 11, where the voice of a hijacker could be heard (see 8:24 a.m. September 11, 2001 and (8:34 a.m.) September 11, 2001). However, none of these had included the hijacker telling people to stay in their seats, as Saracini describes, although the second and third transmissions included the hijacker telling the passengers, “Nobody move.” [9/11 Commission, 7/24/2004, pp. 19] Bottiglia responds: “Oh, okay. I’ll pass that along.” Referring to the fact that this was the end of the transmission he heard, Saracini adds, “It cut out,” and then asks Bottiglia, “Did you copy that?” [Gregor, 12/21/2001 ; Spencer, 2008, pp. 36-37] This is the last radio transmission from Flight 175. The 9/11 Commission will conclude that the plane is hijacked within the next four minutes (see (Between 8:42 a.m. and 8:46 a.m.) September 11, 2001). [9/11 Commission, 8/26/2004, pp. 20] According to author Lynn Spencer, since controllers are only given information on a need-to-know basis, Bottiglia was unaware there were problems with Flight 11, which has not yet entered his airspace. He touches his computer screen to connect to the hotline for his sector controller, and then reports: “UAL 175 just came on my frequency and he said he heard a suspicious transmission when they were leaving Boston. ‘Everybody stay in your seats’—that’s what he heard… just to let you know.” [New York Times, 10/16/2001; Spencer, 2008, pp. 36-37]

Major General Larry Arnold. [Source: US Air Force]Major General Larry Arnold, the commander of the Continental United States NORAD Region (CONR), calls Colonel Robert Marr, the battle commander at NORAD’s Northeast Air Defense Sector (NEADS), who is seeking authorization to scramble fighter jets in response to the hijacked Flight 11, and instructs him to “go ahead and scramble them, and we’ll get authorities later.” [9/11 Commission, 7/24/2004, pp. 20; Spencer, 2008, pp. 38-39] After learning that the FAA wants NORAD assistance with a possible hijacking (see (8:38 a.m.) September 11, 2001), Marr tried calling Arnold at CONR headquarters, at Tyndall Air Force Base, Florida, for permission to scramble fighters from Otis Air National Guard Base in Massachusetts (see (8:38 a.m.) September 11, 2001). Arnold was in a teleconference (see (8:30 a.m.-8:40 a.m.) September 11, 2001), so Marr left a message requesting that Arnold call him back. [Aviation Week and Space Technology, 6/3/2002; Filson, 2003, pp. 55-56; Spencer, 2008, pp. 31] With the teleconference now over, Arnold calls Marr on a secure phone line and is informed of the ongoing situation. [9/11 Commission, 5/23/2003; 9/11 Commission, 2/3/2004 ]Marr Reports Hijacking, Wants to Scramble Fighters - Marr says the FAA’s Boston Center is “reporting a possible hijacked aircraft, real-world, somewhere north of JFK Airport.” He says, “I’ve got Otis [fighters] going battle stations [i.e. with the pilots in the cockpits but the engines turned off] and I’d like to scramble them to military airspace while we try to get approval for an intercept.” Arnold had wondered if the reported hijacking was a simulation, as part of a NORAD training exercise taking place on this day (see (8:40 a.m.) September 11, 2001), and therefore asks, “Confirm this is real-world?” Marr confirms that the hijacking is “real-world.” Marr Lacks Details of Hijacked Flight - Arnold asks where the hijacked aircraft is and Marr replies: “We don’t have a good location. The FAA says they don’t have it on their scopes, but had it west of Boston and thought it was now heading to New York.” Arnold then asks, “Do we have any other information, type, tail, number of souls on board?” to which Marr replies, “I don’t have all the particulars yet, but we’ll pass them on as we get them.” Arnold Tells Marr to Scramble Fighters - According to author Lynn Spencer, in response to Marr’s request to scramble the Otis fighters, “Arnold’s instincts tell him to act first and seek authorizations later.” [Spencer, 2008, pp. 38-39] He therefore says, “Go ahead and scramble them, and we’ll get authorities later.” [Filson, 2003, pp. 56; 9/11 Commission, 7/24/2004, pp. 20] Marr tells Arnold he will “scramble Otis to military airspace” while they try to figure out what is going on. [Grant, 2004, pp. 20] Arnold will later recall that it is his and Marr’s intention to place the fighters in “Whiskey 105”—military airspace over the Atlantic Ocean, just south of Long Island—“since neither he nor Marr knew where the hijacked aircraft was.” [9/11 Commission, 2/3/2004 ] Arnold ends by saying, “Let me know when the jets get airborne,” and adds that he will “run this up the chain” of command. Marr will then direct the NEADS mission crew commander to issue the scramble order (see 8:45 a.m. September 11, 2001). Meanwhile, Arnold will call the NORAD operations center in Cheyenne Mountain, Colorado, about the hijacking, and officers there tell him they will contact the Pentagon to get the necessary clearances for the scramble (see (8.46 a.m.) September 11, 2001). [Filson, 2003, pp. 56; Spencer, 2008, pp. 39]

Craig Marquis, the manager on duty at the American Airlines System Operations Control (SOC) center in Fort Worth, Texas, instructs Peggy Houck, a dispatcher at the SOC, to calculate how far Flight 11 could travel with the fuel it has left. [American Airlines, 9/11/2001, pp. 20-22; 9/11 Commission, 11/19/2003 ; 9/11 Commission, 1/8/2004 ] Marquis was recently told by a colleague at the SOC that FAA air traffic controllers are treating Flight 11 as a hijacking (see 8:40 a.m. September 11, 2001). [9/11 Commission, 11/19/2003 ; 9/11 Commission, 7/24/2004, pp. 6] He now talks to Houck and tells her that Flight 11 has “turned off his transponder.” He says controllers have the plane “on primary radar and they see him descending.” Marquis then asks Houck to calculate how far the plane could go with its current amount of fuel. He says: “Could you run me a model? [Flight 11] is currently 66,000 pounds of gas back from the time I got the call. Just give me some sort of endurance for 25,000 feet, if you would.” [American Airlines, 9/11/2001, pp. 20-22] Marquis is also on the phone with Nydia Gonzalez, a supervisor at the American Airlines Southeastern Reservations Office in North Carolina who is simultaneously participating in a call with Betty Ong, a flight attendant on Flight 11. [9/11 Commission, 11/19/2003 ; 9/11 Commission, 8/26/2004, pp. 8-9] Marquis updates Gonzalez on what is happening. He tells her, “I have the dispatcher currently taking the current fuel on board, and we’re gonna run some profiles to see exactly what [Flight 11’s] endurance is.” [American Airlines, 9/11/2001, pp. 20-22] Houck will perform an analysis of the fuel capacity of Flight 11 and determine that the plane has “an approximate range of six hours.” [Federal Bureau of Investigation, 9/11/2001, pp. 5-7] She will tell the 9/11 Commission that, around this time, she thinks the situation with Flight 11 is “looking like a typical hijacking.… She was thinking they might be headed to Cuba or Colombia.” [9/11 Commission, 1/8/2004 ]

According to the 9/11 Commission, Flight 175 is hijacked some time between 8:42—when its flight crew make their last communication with the ground—and 8:46. The Commission describes that the hijackers “used knives (as reported by two passengers and a flight attendant), Mace (reported by one passenger), and the threat of a bomb (reported by the same passenger). They stabbed members of the flight crew (reported by a flight attendant and one passenger). Both pilots had been killed (reported by one flight attendant).” These witness accounts come from phone calls made from the rear of the plane, from passengers who’d been assigned seats in the front or middle of the cabin. According to the Commission, this is “a sign that passengers and perhaps crew [are] moved to the back of the aircraft.” [9/11 Commission, 7/24/2004, pp. 7; 9/11 Commission, 8/26/2004, pp. 20] An employee at the FAA’s Boston Center later says the hijacking occurs when Flight 175 is above Albany, NY, about 140 miles north of New York City. [Telegraph (Nashua), 9/12/2001; Associated Press, 9/13/2001] The first “operational evidence” that something is wrong is at 8:47, when Flight 175’s transponder code changes twice within a minute (see 8:46 a.m.-8:47 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 7]

Senior United Airlines personnel are, unusually, not informed about air traffic control communications with Flight 175. At 8:41 a.m., the pilots of Flight 175 reported to air traffic controllers that they heard “a suspicious transmission” from another aircraft during their departure out of Boston (see 8:41 a.m.-8:42 a.m. September 11, 2001). Yet the details of this communication with Flight 175 are not passed on to personnel at the United Airlines System Operations Control (SOC) center, just outside Chicago. [9/11 Commission, 8/26/2004, pp. 20]Manager Receives 'No Relevant Information about the Hijackings' - Rich Miles, the manager on duty at the SOC, will later tell the 9/11 Commission that “[w]hile his experience and expectation was that [FAA air traffic control] would communicate to him and to the SOC about ‘strange’ or unusual communications from the cockpit… he could not recall any such communications on 9/11.” He will say that although, “typically, he would receive relevant information from the [air traffic control] system,” he receives “no relevant information about the hijackings” on this day. [9/11 Commission, 11/21/2003 ]Other Airline Personnel Unaware of Flight 175 Communications - None of the other senior United Airlines officials on duty at the SOC are told about the 8:41 a.m. report made by the pilots of Flight 175. [9/11 Commission, 8/26/2004, pp. 20] These officials will tell the 9/11 Commission that “the dispatchers and managers at the SOC” are in fact “not aware of any communications” between FAA controllers and Flight 175 this morning. [9/11 Commission, 11/20/2003 ] The 9/11 Commission will describe, “SOC personnel at United that we talked to had no idea of the extent of interaction of the [Flight 175] crew with the saga of [Flight 11].” The Commission will add, “We walked down a list of indicators,” but state, “Until we mentioned them, no one we talked to [at United Airlines] was aware of those occurrences.” [9/11 Commission, 11/17/2003 ]Controllers Communicate with Pilots, Not Dispatchers - The United Airlines officials will say, however, that, “first and foremost,” FAA controllers “communicated directly with airline pilots, not the dispatchers” at the airline. [9/11 Commission, 11/20/2003 ] Ed Ballinger, the United Airlines dispatcher responsible for Flight 175, will comment that “he did not feel that [air traffic control] was under any obligation to share such information [as the details of the 8:41 a.m. communication] with him, because it didn’t apparently affect the safety of any of his flights.” [9/11 Commission, 4/14/2003 ]Airline Not Advised to Notify Other Planes about Hijackings - The United Airlines officials who talk with the 9/11 Commission will also recall that “they never received any communication… from the FAA or the air traffic control system advising United to contact its aircraft about the hijackings.” The 9/11 Commission will not offer any explanation for the lack of communication between air traffic control and United Airlines. [9/11 Commission, 8/26/2004, pp. 20]

According to an employee at the FAA’s Boston Center in Nashua, New Hampshire, Flight 11 and Flight 175 nearly crash into each other while heading toward their targets in New York. The unnamed employee says, “The two aircraft got too close to each other down by Stewart” International Airport, which is in New Windsor, NY, about 55 miles north of New York City. Describing the incident, the Nashua Telegraph says that the terrorists “nearly had their plans dashed when the two planes almost collided.” [Telegraph (Nashua), 9/12/2001; Associated Press, 9/13/2001; United Press International, 9/13/2001] It is unclear exactly when this incident occurs, though it is presumably shortly after 8:42, when Flight 175 has its last communication with air traffic control. [9/11 Commission, 7/24/2004, pp. 7]

Craig Marquis, the manager on duty at the American Airlines System Operations Control center in Fort Worth, Texas, is told that the American Airlines Southeastern Reservations Office in North Carolina has lost contact with Betty Ong, a flight attendant on the hijacked Flight 11, and he then says he wants the reservations office employees to keep quiet about the hijacking. [American Airlines, 9/11/2001, pp. 20-22; 9/11 Commission, 8/26/2004, pp. 14] Marquis is on the phone with Nydia Gonzalez, a supervisor at the reservations office who, for over 20 minutes, has been relaying to him information she was receiving in a simultaneous phone call with Ong (see (8:21 a.m.) September 11, 2001). [9/11 Commission, 11/19/2003 ; 9/11 Commission, 8/26/2004, pp. 8-9] Ong, however, has stopped responding to communications (see (8:43 a.m.) September 11, 2001). Gonzalez promptly informs Marquis of this. She tells him, “I think we might have lost her.” Marquis says, “Okay,” and then tells Gonzalez, “If in fact she calls back, you call me back.” Gonzalez agrees to do this. Marquis Tells Gonzalez to Keep Quiet about Hijacking - Marquis then tells Gonzalez that he wants her and her colleagues to keep quiet about the hijacking of Flight 11. He says, “I don’t want this spread all over.” Gonzalez has already instructed the other reservations office employees who were on the phone with Ong to keep quiet about the hijacking (see 8:31 a.m. September 11, 2001), and agrees to Marquis’s request. She answers: “Right. I’ve already made that indication to our people here.” Marquis says, “Try to make sure that it’s followed through on, okay?” Gonzalez replies, “Okay.” Just before the call between Marquis and Gonzalez ends, Marquis tells Gonzalez, “I’ll be back in touch with you.” Gonzalez then says, “I’m gonna stay on the line with my agent just in case we get the line [with Ong] back, and I’ll call you back.” [American Airlines, 9/11/2001, pp. 20-22]

An emergency locator transmitter (ELT). [Source: ELTA]A special radio transmitter that is carried by aircraft and designed to go off automatically if a plane crashes is activated in the New York area, more than two minutes before Flight 11 hits the World Trade Center. [New York Times, 10/16/2001; 9/11 Commission, 10/1/2003 ; Aircraft Owners and Pilots Association, 1/22/2009]Pilots Inform Controller of Emergency Signal - At 8:44 a.m. and 5 seconds, David Bottiglia, an air traffic controller at the FAA’s New York Center, receives information from one of the aircraft he is monitoring. The pilot of US Airways Flight 583 tells him: “I just picked up an ELT [emergency locator transmitter] on 121.5. It was brief, but it went off.” [New York Times, 10/16/2001; 9/11 Commission, 10/1/2003 ] (121.5 megahertz is an emergency frequency that ELTs transmit their distress signals on. [Aircraft Electronics Association, 2009, pp. 36 ; Aircraft Owners and Pilots Association, 1/22/2009] ) A minute later, at 8:45 a.m. and 8 seconds, Bottiglia hears the same thing from another of the aircraft he is monitoring. The pilot of Delta Airlines Flight 2433 tells him, “We picked up that ELT too, but it’s very faint.” [New York Times, 10/16/2001] However, Flight 11 has not yet crashed, and will hit the WTC over 90 seconds later, at 8:46 a.m. and 40 seconds (see 8:46 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 7]ELTs Help Locate Crashed Aircraft - An emergency locator transmitter, or ELT, is a small electronic device, which is designed to automatically begin emitting a continuous and distinctive radio signal when subjected to crash-generated forces, so as to facilitate the locating of an aircraft if it crashes. ELTs are carried aboard most general aviation aircraft in the US and are usually located far back in the plane’s fuselage or in the tail surface, so that they will suffer only minimal damage in the event of a crash impact. [Federal Aviation Administration, 3/23/1990; US Department of the Army, 8/12/2008, pp. E-6 ; Aircraft Electronics Association, 2009, pp. 36 ; Aircraft Owners and Pilots Association, 1/22/2009]Location Signal Comes from Unclear - The precise location from where the ELT signal is being transmitted is unclear. Around the time Flight 11 crashes, a participant in an FAA teleconference will say the signal was coming from the area Flight 11’s track was in before it disappeared from primary radar, about 20 miles from New York’s JFK International Airport. [Federal Aviation Administration, 9/11/2001] Peter McCloskey, a traffic management coordinator at the New York Center, will tell the 9/11 Commission that the ELT goes off “in the vicinity of Lower Manhattan.” [9/11 Commission, 10/1/2003 ]Many Signals Are False Alarms - ELT signals not determined to be false alarms are reported to the Air Force Rescue Coordination Center (AFRCC) at Langley Air Force Base in Virginia. [9/11 Commission, 10/1/2003 ] Major Allan Knox, who works at the AFRCC, will tell the 9/11 Commission that he does not recall being informed of any ELT signals on September 11, but says the AFRCC will review its data to verify this statement. He will also say that at least 20 ELT signals go off each day, and that 97 percent of ELT signals are false alarms. [9/11 Commission, 10/6/2003 ]ELT Signal Is 'Clearly Indicative of a Crash' - However, Paul Thumser, an operations supervisor at the FAA’s New York Center with 20 years’ experience as an air traffic controller, and who is also an experienced airline pilot, will tell the 9/11 Commission that the ELT in a Boeing 767 cannot be triggered by the pilot. (The two aircraft that hit the WTC are 767s.) He will also say that the sensitivity setting for the ELT in a 767 is not low, and so it should be impossible for a hard turn or a hard landing to accidentally cause the ELT to go off. Thumser will say that “he judged it would have to be a serious impact to set the ELT off.” [9/11 Commission, 10/1/2003 ] Terry Biggio, the operations manager at the FAA’s Boston Center, will similarly tell the 9/11 Commission that an ELT signal “is clearly indicative of a crash.” [9/11 Commission, 9/22/2003]FAA Manager Believes Signal Unrelated to Flight 11 Crash - Noting that the ELT goes off prior to Flight 11 hitting the WTC, Mike McCormick, the manager of the FAA’s New York Center, will tell the 9/11 Commission that his “best hypothesis” is that the activation of an ELT at this time is “unrelated to the event” of Flight 11 crashing. [9/11 Commission, 12/15/2003 ] However, there are no reports of an ELT going off at the time when Flight 11 hits the WTC. Furthermore, another ELT will be activated in the New York area around five minutes before the second plane hits the WTC (see 8:58 a.m. September 11, 2001). [Federal Aviation Administration, 9/11/2001, pp. 37 ] Despite the pilots’ reports of picking up an ELT signal just before Flight 11 crashes, the AFRCC will inform the 9/11 Commission that a “historical ELT data search” found “no ELT signal being heard by the satellites” for the area within a radius of 50 nautical miles (about 57.5 miles) of JFK International Airport between 8:00 a.m. and 10:30 a.m. on this day.

John Mica. [Source: Publicity photo]Defense Secretary Donald Rumsfeld, Deputy Defense Secretary Paul Wolfowitz, Representatives Christopher Cox (R-CA) and John Mica (R-FL), and numerous others are meeting in Rumsfeld’s private Pentagon dining room, discussing missile defense (see (8:00 a.m.-8:50 a.m.) September 11, 2001). Rumsfeld later recalls, “I had said at an eight o’clock breakfast that sometime in the next two, four, six, eight, ten, twelve months there would be an event that would occur in the world that would be sufficiently shocking that it would remind people again how important it is to have a strong healthy Defense Department that contributes to—that underpins peace and stability in our world.” [US Department of Defense, 12/5/2001] Wolfowitz recalls, “And we commented to them that based on what Rumsfeld and I had both seen and worked on the Ballistic Missile Threat Commission, that we were probably in for some nasty surprises over the next ten years.” [Vanity Fair, 5/9/2003] According to Mica, “the subject of the conversation Donald Rumsfeld was interested in was, the military had been downsized during the ‘90s since the fall of the Berlin Wall. And what we were going to do about [the] situation if we had another—the word [Rumsfeld] used was ‘incident.‘… And he was trying to make certain that we were prepared for something that we might not expect.” [US Congress. House. Oversight and Government Reform Committee, 8/1/2007] There are confused accounts that Rumsfeld says, “I’ve been around the block a few times. There will be another event,” just before the Pentagon is hit by Flight 77 (see (Before 9:37 a.m.) September 11, 2001), but such comments may have been made around this time instead. Shortly afterwards, someone walks in with a note informing Rumsfeld that a plane has just hit the WTC (see Shortly After 8:46 a.m. September 11, 2001). [US Department of Defense, 12/5/2001; 9/11 Commission, 3/23/2004] Mica later comments, “[L]ittle did we know that within a few minutes of the end of our conversation and actually at the end of our breakfast, that our world would change and that incident that we talked about would be happening.” [US Department of Defense, 9/10/2004]

General Ralph Eberhart, the commander of NORAD, learns that a plane has been hijacked and then drives to his office, where he sees the television reports showing an aircraft has crashed into the World Trade Center, but he does not initially realize a terrorist attack is taking place. Eberhart has just arrived back at his home in Colorado after going for a jog when, at around 8:45 a.m., he receives a call from Captain Michael Jellinek, command director at NORAD’s operations center in Cheyenne Mountain. Jellinek tells Eberhart that the FAA has reported a suspected hijacking on the East Coast. He says this is a “real-world” hijacking and not part of an exercise, and that NORAD has authorized the scrambling of fighter jets in response. Eberhart will later recall that he isn’t “too excited” about the incident at this time and is thinking it is a “traditional” hijacking. Shortly after receiving the call, he drives to his office, at NORAD’s headquarters at Peterson Air Force Base in Colorado Springs. He arrives there at around 9:00 a.m. to 9:10 a.m., he will recall, and then sees CNN’s coverage of the burning WTC on television. He calls the Cheyenne Mountain Operations Center and asks if the aircraft that crashed into the WTC was the plane that was suspected of being hijacked. The person he speaks to says reports on CNN indicated that a small aircraft, and not the hijacked commercial aircraft, hit the WTC. There is apparently “great confusion in the system” at this time, Eberhart will comment. He will say the information NORAD currently has is only as good as what the FAA has provided. Eberhart will see the second hijacked plane, Flight 175, crashing into the WTC live on television at 9:03 a.m. and then realize that a coordinated terrorist attack is taking place (see (9:03 a.m.-9:30 a.m.) September 11, 2001). [9/11 Commission, 3/1/2004; 9/11 Commission, 3/1/2004 ; 9/11 Commission, 3/1/2004; 9/11 Commission, 3/1/2004]

Joseph Bertapelle. [Source: Publicity photo]American Airlines managers are informed of what their airline has learned about the trouble on Flight 11 during a regular conference call. [Wall Street Journal, 10/15/2001; 9/11 Commission, 11/19/2003 ] In their daily morning conference call, senior American Airlines personnel usually discuss what happened on the previous day at the airline and what they are expecting in the day ahead. [9/11 Commission, 1/7/2004 ] But shortly after today’s conference call begins, Joseph Bertapelle, a manager at the airline’s System Operations Control (SOC) center in Fort Worth, Texas, announces, “Gentlemen, I have some information here I need to relay.” [Wall Street Journal, 10/15/2001] Bertapelle then passes on to the senior managers much of the information about the hijacking of Flight 11 that has been received by SOC employees Craig Marquis and Bill Halleck. Marquis, the manager on duty at the SOC, has been on the phone with a supervisor at the American Airlines Southeastern Reservations Office in North Carolina, who has been relaying to him information she received in a simultaneous phone call with Betty Ong, a flight attendant on Flight 11 (see (8:21 a.m.) September 11, 2001). [9/11 Commission, 11/19/2003 ; 9/11 Commission, 8/26/2004, pp. 8-9] And Halleck, an air traffic control specialist at the SOC, has been in contact with the FAA’s Boston Center, which gave him details of the problems with Flight 11 (see 8:29 a.m. September 11, 2001). [9/11 Commission, 3/25/2004, pp. 15] The conference call apparently only lasts a short time. Craig Parfitt, American Airlines’ managing director of dispatch operations, will later recall that at around 8:55 a.m.—10 minutes after the conference call begins—senior managers are arriving at the System Operations Command Center, located on the floor above the SOC (see (Between 8:40 a.m. and 8:55 a.m.) September 11, 2001). Presumably, some of these managers will have previously been participating in the conference call. [9/11 Commission, 11/19/2003 ]

Larry Wansley. [Source: Publicity photo]At 8:45 a.m., Larry Wansley learns of the hijacking of Flight 11. Wansley is the managing director of corporate security for American Airlines, and is at the company’s headquarters in Fort Worth, Texas. He is informed of the hijacking in an urgent phone call from the airline’s Command Center, located on the floor above its System Operations Control (SOC), about a mile away from headquarters (see (Between 8:40 a.m. and 8:55 a.m.) September 11, 2001). The SOC learned there was some kind of problem with Flight 11 at 8:20 a.m. (see 8:20 a.m. September 11, 2001). Since as early as 8:21, details of Flight 11 attendant Betty Ong’s emergency call have been constantly relayed to Craig Marquis, a manager at the SOC (see 8:21 a.m. September 11, 2001). Yet the 8:45 call is apparently Wansley’s first notification of the hijacking. He calls Danny Defenbaugh, the special agent in charge of the Dallas FBI office. Wansley is himself a former undercover FBI agent, and Defenbaugh is a longtime friend of his. This call is “the first step in the well-researched, secret hijack-response plan all commercial airlines have in place.” As Wansley is relaying information, he hears screaming from an adjacent conference room, as several employees watch the aftermath of the first WTC crash on television. The TV in Defenbaugh’s office has been turned on, but reportedly neither of the two men connects the images of the burning tower with the hijacking they are trying to deal with. As they continue discussing their response plans, television shows the second plane hitting the South Tower. No doubt realizing this is a terrorist attack, Defenbaugh says, “The ball game just changed.” Around this time, Wansley learns that the first plane to hit the WTC was the hijacked American Airlines flight. He will subsequently make a hurried drive to the nearby Command Center, where the FBI will already be setting up its own command post (see Shortly After 8:46 a.m. September 11, 2001).

The US Strategic Command command center. [Source: US Strategic Command]At the time the attacks in New York occur, a small group of business leaders are having breakfast at Offutt Air Force Base in Omaha, Nebraska, where the US Strategic Command (Stratcom) is headquartered. With them is Admiral Richard Mies, the commander in chief of Stratcom. They are in town for an annual charity fundraiser event due to take place later in the day, hosted by the multi-billionaire Warren Buffett. Along with other visitors who have come for the fundraiser, they are scheduled to tour the Stratcom underground command center, located 60 feet below Offutt, and receive an unclassified mission briefing. According to the Omaha World-Herald, staff members have left the command center in advance of their visit. It is only after the second attack occurs, at 9:03, that Admiral Mies excuses himself from the breakfast and the battle staff reconvenes in the center. [San Francisco Business Times, 2/1/2002; Omaha World-Herald, 2/27/2002] It is unclear what effect the absence of Mies and the members of the battle staff have upon the military’s ability to respond effectively to the first attacks. However, the command center does have significant capabilities that would, presumably, be of much use under such a crisis. Stratcom is the military command responsible for the readiness of America’s nuclear forces. [Arkin, 2005, pp. 59] The Lincoln Journal Star describes its underground command center as “a military nerve center that collects and assesses information from high-tech ‘eyes and ears’ across—and above—the globe.” [Journal Star (Lincoln), 10/25/2000] The cavernous room has eight giant video screens and complex communications systems. [Associated Press, 2/21/2002; Omaha World-Herald, 2/27/2002] Stratcom itself states that the senior controller in the command center “has a direct line to the National Military Command Center in Washington, DC, and to the other major command headquarters.” This system, called the Joint Chiefs of Staff Alerting Network, allows the commander in chief of Stratcom to make “prompt contact with the president, the secretary of defense, the chairman of the Joint Chiefs of Staff, and other unified commanders.” Furthermore, “Through satellites and radio networks (VLF, LF, UHF and HF), the command center can communicate with aircraft in flight over any part of the world. A principal purpose of these networks is to pass National Command Authority [i.e. the president and secretary of defense] orders to the alert forces.” While only the president can order nuclear strikes, the commander in chief of Stratcom “can launch aircraft for survival.” [United States Strategic Command, 6/22/2001] With the command center’s sophisticated capabilities, after Mies returns to it from his breakfast, the eight video screens there are “loaded up with data,” providing him with “the latest information on the unfolding drama.” [Omaha World-Herald, 2/27/2002] And at the time President Bush arrives at Offutt, later in the day (see 2:50 p.m. September 11, 2001), the battle staff in the center will reportedly be “watching the skies over the United States” and “tracking a commercial airliner on its way from Spain to the United States.” [Washington Post, 1/27/2002; CBS News, 9/11/2002]

CNN will report that, while Flight 11 is heading toward the World Trade Center, “[S]ources say there were bomb threats called in to air traffic control centers adding to the chaos.” One center receiving such threats is the FAA’s Boston Center, which handles air traffic over New England and monitors flights 11 and 175. The FAA’s Cleveland Center, which will monitor Flight 93, receives similar threats (see 10:07 a.m.-10:21 a.m. September 11, 2001). Whether other centers are threatened is unstated. According to Newsweek, “Officials suspect that the bomb threats were intended to add to the chaos, distracting controllers from tracking the hijacked planes.” [Newsweek, 9/22/2001; CNN, 9/30/2001] Yet, just weeks after 9/11, the Washington Post will claim: “Federal aviation officials no longer believe that accomplices of the hijackers made phony bomb threats to confuse air traffic controllers on September 11. Sources said reports of multiple threats were apparently the result of confusion during the early hours of the investigation and miscommunication in the Federal Aviation Administration.” [Washington Post, 9/27/2001]

Master Sergeant Joe McCain, the mission crew commander technician at NORAD’s Northeast Air Defense Sector (NEADS), believes he has located Flight 11 on the radar screen and then watches it disappear over New York, but he does not realize it has crashed. McCain is on the phone with Colin Scoggins, the military liaison at the FAA’s Boston Center. [Spencer, 2008, pp. 40-41] NEADS personnel have been unable to locate Flight 11 on their radar screens (see Shortly After 8:37 a.m. September 11, 2001). [Utica Observer-Dispatch, 8/5/2004]McCain Locates Fast-Moving Aircraft - Now McCain believes he has found Flight 11, flying about 20 miles north of Manhattan. According to author Lynn Spencer, he “knows that planes tend to fly very specific routes, like highways in the sky, and this particular target seems not to be on any of those regular routes. It’s also very fast moving.” McCain tells Scoggins, “I’ve got a search target that seems to be on an odd heading here,” and then describes its location. Scoggins notices the target, but this is not Flight 11. Scoggins then realizes that Flight 11 is right behind the target McCain has identified, and yells to him: “There’s a target four miles behind it, that’s the one! That’s American 11!” McCain responds, “I’ve got it!” The aircraft is 16 miles north of New York’s JFK International Airport, and heading down the Hudson River valley. NEADS has no altitude for it, but the aircraft is clearly traveling very fast. After hanging up the phone, McCain calls out its coordinates to everyone on the NEADS operations floor. [Spencer, 2008, pp. 40] McCain will later recall: “It’s very unusual to find a search target, which is a plane with its transponder turned off, in that area. This plane was headed toward New York going faster than the average Cessna and was no doubt a jet aircraft. We had many clues. The plane was fast and heading in an unusual direction with no beacon. We had raw data only. Everything just kind of fit.” [Filson, 2003, pp. 56-57] (The identity of the other fast-moving aircraft McCain had noticed, four miles ahead of Flight 11, is unstated.) Flight 11 Disappears from Radar - Less than a minute after McCain locates the track for Flight 11, it disappears. [Spencer, 2008, pp. 41] McCain will recall, “We watched that track until it faded over New York City and right after that someone came out of the break room and said the World Trade Center had been hit.” [Filson, 2003, pp. 57] However, McCain supposedly does not realize that the plane he had spotted has crashed into the WTC. According to Spencer: “[H]e knows only that the blip he has struggled so mightily to locate has now vanished. He figures that the plane has descended below his radar coverage area to land at JFK. The fact that the plane was flying much too fast for landing does not hit him; the concept that the plane might have been intentionally crashed is simply too far outside his realm of experience.” [Spencer, 2008, pp. 41]

CIA Director George Tenet is eating breakfast with his mentor, former Senator David Boren (D-OK), at the St. Regis Hotel, three blocks north of the White House. According to journalist Bob Woodward, Boren asks Tenet, “What are you worried about these days?” Tenet replies, “Bin Laden,” and says he is convinced the al-Qaeda leader is going to do something big. Boren asks him how could one person without the resources of a foreign government be such a threat? Tenet responds, “You don’t understand the capabilities and the reach of what they’re putting together.” [Woodward, 2002, pp. 1 and 3; Chicago Sun-Times, 12/6/2002] When, shortly afterwards, Tenet learns of the first attack on the World Trade Center, he will immediately say he thinks bin Laden is responsible (see (8:50 a.m.) September 11, 2001).

Soldier firing a Stinger missile. [Source: US Army]In New York, the Secret Service has a Stinger missile secretly stored in the World Trade Center, to be used to protect the president if the city were attacked when he visits it. Presumably it keeps this is in WTC Building 7, where its field office is. [Tech TV, 7/23/2002; Weiss, 2003, pp. 379] Stinger missiles provide short-range air defense against low-altitude airborne targets, such as fix-winged aircraft, helicopters, and cruise missiles. They have a range of between one and eight kilometers. [Federation of American Scientists, 8/9/2000; GlobalSecurity (.org), 4/27/2005] Whether the Secret Service makes any attempt at defending New York from the two attacking planes with its Stinger missile is unknown. The agency is also known to have air surveillance capabilities. These include a system called Tigerwall, which provides “early warning of airborne threats” and “a geographic display of aircraft activity” (see (September 2000 and after)). And according to Barbara Riggs, who is in the Secret Service’s Washington, DC headquarters on this day, the agency is “able to receive real time information about other hijacked aircraft,” through “monitoring radar and activating an open line with the FAA.” [US Department of the Navy, 9/2000, pp. 28 ; PCCW Newsletter, 3/2006; Star-Gazette (Elmira), 6/5/2006] These capabilities would presumably be of use if the Secret Service wanted to defend the World Trade Center. Furthermore, according to the British defense publication Jane’s Land-Based Air Defence, “the American president’s residences in Washington and elsewhere are protected by specialist Stinger teams in case of an aerial attack by terrorist organizations.” [Jane's Land-Based Air Defence, 10/13/2000] Knight Ridder has previously reported “several sources” telling it, “Stinger missiles are in the Secret Service’s arsenal.” [Knight Ridder, 9/12/1994] And according to the London Telegraph, the Secret Service is “believed to have a battery of ground-to-air Stinger missiles” ready to defend the White House. [Daily Telegraph, 9/16/2001] Flight 77 reportedly comes within four miles of the White House before turning toward the Pentagon. [ABC News, 10/24/2001; USA Today, 8/12/2002] Whether the Secret Service makes any attempt at defending the place with its Stinger missiles is unknown. However, the Washington Post will later claim it is an “urban legend that Stinger missiles are mounted on the White House roof.” [Washington Post, 4/4/2002]

Dell Dailey. [Source: US Department of State]Members of the Joint Special Operations Command (JSOC)—the nation’s “top counterterrorism unit”—are away from America when it comes under terrorist attack, participating in a training exercise in Hungary. [Naylor, 2015, pp. ix-x; Newsweek, 9/11/2015] The highly classified exercise, called Jackal Cave, is one of several joint readiness exercises that JSOC conducts each year. It is part of a larger exercise, called Ellipse Bravo, run by the US military’s European Command (see (After 9:03 a.m.) September 11, 2001). [Arkin, 2005, pp. 358-359; Naylor, 2015, pp. ix] Jackal Cave involves participants tracking down a hypothetical hybrid force made up of terrorists and elements of international organized crime who are trafficking in weapons of mass destruction. “We were tracking ‘terrorists,’” a JSOC staff officer will later comment. “[A]nd then [we’d] bring an assault element in to take the target down.” Details of the mock terrorists in the exercise are unclear, but they are not Islamists, according to journalist and author Sean Naylor. [Naylor, 2015, pp. x, 441]JSOC and Delta Force Are Participating in the Exercise - Jackal Cave involves over 500 personnel, 62 aircraft, and 420 tons of cargo. [Arkin, 2005, pp. 404] Hundreds of JSOC personnel are taking part. [Naylor, 2015, pp. 85] JSOC, based at Fort Bragg and Pope Air Force Base in North Carolina, is responsible for conducting the US military’s most sensitive counterterrorism missions. [New York Times, 9/3/2002; GlobalSecurity (.org), 6/24/2013] Its headquarters for the exercise is divided between Taszár Air Base, about 120 miles southwest of Budapest, Hungary, and Tuzla, Bosnia. A squadron from the US Army’s Delta Force is also participating in the exercise. [Fury, 2008, pp. 56; Saratogian, 9/10/2011; Naylor, 2015, pp. x] Delta Force is designed to be an overseas counterterrorist unit and specializes in hostage rescue, barricade operations, and reconnaissance. [GlobalSecurity (.org), 6/24/2013] Its personnel are trained in dealing with terrorist situations in buildings and hijacked aircraft, among other things. [Discovery Channel, 12/1/2001; Haney, 2002, pp. 213; Schading and Schading, 2006, pp. 156]Mock Terrorists Are Played by US Military Personnel - Others taking part in Jackal Cave include members of the US Army’s 10th Special Forces Group, members of the Department of Energy’s Nuclear Emergency Search Team (see (September 10-15, 2001)), and some Hungarian military elements. [Richelson, 2009, pp. 178; Jeffrey T. Richelson, 1/23/2009; Naylor, 2015, pp. x] The terrorists in the exercise are being played by operatives from the Defense HUMINT Service—the US Defense Department’s clandestine spy network. Members of the US Navy’s SEAL Team Six are also taking part and are in the port of Dubrovnik, Croatia, from where the hypothetical enemy is trying to ship nuclear material out on a boat. The SEALs are going to be flown by helicopter to assault the boat in the Mediterranean Ocean. JSOC Commander Learns of the Attacks in the US and Cancels the Exercise - At the time the attacks on the World Trade Center take place, Jackal Cave has barely started. One or two Delta Force staffers and some operatives with the Operational Support Troop—Delta Force’s in-house intelligence arm—are out tracking the mock terrorists through downtown Budapest. Meanwhile, Major General Dell Dailey, head of JSOC, is at the US embassy in Budapest, where he has been briefing senior officials on the exercise. He learns about the attacks on the WTC after leaving the briefing with his senior enlisted adviser, Army Command Sergeant Major Mike Hall. Major Jim Reese, a Delta Force officer, sees the coverage of the burning Twin Towers on television and then runs after the two men. He tells Dailey, “Hey sir, you need to see this.” Dailey quickly walks to his operations center at the embassy and sees the coverage of the attacks on TV. He then answers a phone call from his boss, Air Force General Charles Holland, head of US Special Operations Command at MacDill Air Force Base in Tampa, Florida. Holland tells him to abandon the exercise and return to the US as quickly as possible. After hanging up, Dailey turns to Reese and Lieutenant Colonel Scott Miller, another Delta Force officer, and says he is canceling the exercise immediately and returning to the US, and they should get back to the US too. However, as America’s airspace is closed to international commercial flights for several days following today’s attacks, it will take almost a week for the JSOC personnel who are in Europe for the exercise to return to America.

Michael Jellinek. [Source: Tom Kimmell]The NORAD operations center in Cheyenne Mountain, Colorado, receives a call notifying it that the FAA has requested military assistance with a hijacking, and senior officers there agree with the decision that has been made to launch fighter jets in response to the hijacking, and say they will call the Pentagon to get the necessary clearance for this. [Filson, 2003, pp. 56; 9/11 Commission, 3/1/2004 ; Spencer, 2008, pp. 39] Major General Larry Arnold, the commander of the Continental United States NORAD Region, has just talked over the phone with Colonel Robert Marr at NORAD’s Northeast Air Defense Sector (NEADS), and Marr suggested to him that fighters be scrambled in response to the hijacked Flight 11. Arnold told Marr to go ahead with the scramble and said he would sort out getting authorization for it (see (8:42 a.m.) September 11, 2001). Arnold therefore now calls the Cheyenne Mountain Operations Center (CMOC). The call is answered by Captain Michael Jellinek, the command director on duty there. [Aviation Week and Space Technology, 6/3/2002; Spencer, 2008, pp. 38-39] Arnold says the FAA has requested assistance for an ongoing hijacking. [9/11 Commission, 3/1/2004 ]NORAD Director Approves Decision to Launch Fighters - Jellinek passes on the details of the request to Major General Rick Findley, NORAD’s director of operations, who has just finished the night shift and is returning to the CMOC battle cab from breakfast. Jellinek will later recall: “I pick up the other phone because I know [Findley is] there. One button and I’m talking to him. It’s faster to do that than walk around the window, say the same thing.” [Calgary Herald, 10/1/2001; Canadian Broadcasting Corporation, 11/27/2001; Toronto Star, 12/9/2001] Findley “concurs with Arnold’s assessment and decision to scramble the fighters,” according to author Lynn Spencer, and quickly approves the fighters’ launch. [Aviation Week and Space Technology, 6/3/2002; Spencer, 2008, pp. 39] He “immediately gives the thumbs up” through the window, according to Jellinek. [Canadian Broadcasting Corporation, 11/27/2001] Arnold will say he is told (presumably by Jellinek): “Yeah, we’ll work this with the National Military Command Center [at the Pentagon]. Go ahead and scramble the aircraft.” [Filson, 2002; Filson, 2003, pp. 56] According to Findley: “At that point, all we thought was we’ve got an airplane hijacked and we were going to provide an escort as requested [by the FAA]. We certainly didn’t know it was going to play out as it did.” [Ottawa Citizen, 9/11/2002]NORAD Personnel Request Permission for Scramble - Findley will say that after the CMOC receives the call from Arnold, he “knew what to do, and so did everybody else on the battle staff.” He tells the members of the battle staff to “open up our checklist” and “follow our NORAD instruction,” which includes having “to ask in either Ottawa or Washington, ‘Is it okay if we use NORAD fighters to escort a potential hijacked aircraft?’” [CNN, 9/11/2006] Findley and the others in the CMOC will subsequently see the coverage on CNN, reporting that a plane has hit the World Trade Center, but do not initially realize the plane involved was the hijacked aircraft they have been called about (see (8:48 a.m.) September 11, 2001).

Flight 11 hits the WTC North Tower at 8:46. This video still is the only well-known image of this crash (from the French documentary). [Source: Gamma Press]Two French documentary filmmakers are filming a documentary on New York City firefighters about ten blocks from the WTC. One of them hears a roar, looks up, and captures a distant image of the first WTC crash. They continue shooting footage nonstop for many hours, and their footage is first shown that evening on CNN. [New York Times, 1/12/2002] President Bush later claims that he sees the first attack live on television, but this is technically impossible, as there was no live news footage of the attack. [Wall Street Journal, 3/22/2004 ]

Flight 175 stops transmitting its transponder signal. It is currently flying near the New Jersey-Pennsylvania border. [Guardian, 10/17/2001; Newsday, 9/10/2002; 9/11 Commission, 6/17/2004] However, the transponder is turned off for only about 30 seconds, and then comes back on as a signal that is not designated for any plane on this day. Then, within the space of a minute, it is changed to another new code. But New York Center air traffic computers do not correlate either of these new transponder codes with Flight 175. Consequently, according to an early FAA report, “the secondary radar return (transponder) indicating aircraft speed, altitude, and flight information began to coast and was no longer associated with the primary radar return.” Therefore, while controllers are able “to track the intruder easily… they couldn’t identify it.” However, Dave Bottiglia, the New York Center air traffic controller responsible for Flight 175, is currently trying to locate the already-crashed Flight 11, and therefore supposedly does not notice the transponder code changes on Flight 175 until 8:51 a.m. (see 8:51 a.m.-8:53 a.m. September 11, 2001). [Federal Aviation Administration, 9/17/2001 ; Washington Post, 9/17/2001; 9/11 Commission, 8/26/2004, pp. 21] According to a “Flight Path Study” by the National Transportation Safety Board, the change of Flight 175’s transponder code is the “first indication of deviation from normal routine.” [National Transportation Safety Board, 2/19/2002 ]

Fort AP Hill. [Source: United States Army]At the time of the attacks on the World Trade Center, members of the Army’s aviation support unit for the Washington, DC, area are away for weapons training, and do not set out to return to their base until after the time the Pentagon is hit. [Army Center of Military History, 11/14/2001 ; Pentagram, 11/16/2001; Fort Belvoir News, 1/18/2002] The 12th Aviation Battalion is the Military District of Washington’s aviation support unit, and includes three helicopter companies. It operates UH-1 “Huey” and UH-60 Black Hawk helicopters. The battalion is stationed at Davison Army Airfield, which is at Fort Belvoir, 12 miles south of the Pentagon. [Military District of Washington, 8/2000] Davison Airfield’s missions include maintaining “a readiness posture in support of contingency plans,” exercising “operational control” of the Washington area airspace, and providing “aviation support for the White House, US government officials, Department of Defense, Department of the Army, and other government agencies.” [Pentagram, 5/7/1999] A chief warrant officer with the 12th Aviation Battalion will later recall that members of the battalion are away this morning, at the shooting range at another Virginia Army base, Fort AP Hill, for their annual weapons training. They had set off early and driven there—a journey of one and a half to two hours. They are at the range when the attacks on the WTC take place, and only learn of them when the sister of one of their captains calls her brother with news of the attacks, presumably after seeing the coverage on television. The chief warrant officer will recall that, after hearing of the second attack on the WTC, “[W]e were all pretty much thinking we probably need to go—you know, probably need to come to work.” The range officer calls Davison Airfield and is told that the members of the battalion should “pack it in and come on back” to base. He is also told during the call that an aircraft has crashed into the Pentagon (see 9:37 a.m. September 11, 2001), meaning this call does not occur until after 9:37 a.m. According to the chief warrant officer, the Pentagon “is basically one of our missions. So we just pretty much packed up and came back up here and came into work.” Exactly how many of the 12th Aviation Battalion’s members are away from base for the weapons training is unstated, as is the exact time they arrive back at Davison Airfield. But considering it is one and a half to two hours drive between there and the range, they presumably do not get there until some time after about 11:15 a.m. When they do eventually get back to base, the battalion members will prepare to launch helicopters in response to the Pentagon attack (see (After 11:15 a.m.) September 11, 2001).
